The version of Firefox installed on the remote macOS or Mac OS X host is prior to 60.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-11 advisory.

  - Mozilla developers and community members Christoph Diehl, Christian Holler, Jon Coppeard, Jason Kratzer,     Nathan Froyd, Paul Theriault, Ryan VanderMeulen, Tyson Smith, Sebastian Hengst, Byron Campen, Emilio Cobos     lvarez, Ronald Crane, and Phillipp reported memory safety bugs present in Firefox 59. Some of these bugs     showed evidence of memory corruption and we presume that with enough effort that some of these could be     exploited to run arbitrary code. (CVE-2018-5151)

  - An integer overflow can occur in the Skia library due to 32-bit integer use in an array without integer     overflow checks, resulting in possible out-of-bounds writes. This could lead to a potentially exploitable     crash triggerable by web content. (CVE-2018-5159)

  - A use-after-free vulnerability can occur while enumerating attributes during SVG animations with clip     paths. This results in a potentially exploitable crash. (CVE-2018-5154)

  - A use-after-free vulnerability can occur while adjusting layout during SVG animations with text paths.
    This results in a potentially exploitable crash. (CVE-2018-5155)

  - Same-origin protections for the PDF viewer can be bypassed, allowing a malicious site to intercept     messages meant for the viewer. This could allow the site to retrieve PDF files restricted to viewing by an     authenticated user on a third-party website. (CVE-2018-5157)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-201810-01 (Mozilla Firefox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox. Please       review the referenced CVE identifiers for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page, possibly resulting in the execution of arbitrary code with the       privileges of the process or a Denial of Service condition. Furthermore,       a remote attacker may be able to perform Man-in-the-Middle attacks,       obtain sensitive information, spoof the address bar, conduct clickjacking       attacks, bypass security restrictions and protection mechanisms, or have       other unspecified impact.
  Workaround :

    There is no known workaround at this time.

The version of Firefox ESR installed on the remote Windows host is prior to 52.8. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-12 advisory.

  - Mozilla developers backported selected changes in the Skia library to the ESR52 branch of Firefox. These     changes correct memory corruption issues including invalid buffer reads and writes during graphic     operations. (CVE-2018-5183)

  - A use-after-free vulnerability can occur while enumerating attributes during SVG animations with clip     paths. This results in a potentially exploitable crash. (CVE-2018-5154)

  - A use-after-free vulnerability can occur while adjusting layout during SVG animations with text paths.
    This results in a potentially exploitable crash. (CVE-2018-5155)

  - Same-origin protections for the PDF viewer can be bypassed, allowing a malicious site to intercept     messages meant for the viewer. This could allow the site to retrieve PDF files restricted to viewing by an     authenticated user on a third-party website. (CVE-2018-5157)

  - The PDF viewer does not sufficiently sanitize PostScript calculator functions, allowing malicious     JavaScript to be injected through a crafted PDF file. This JavaScript can then be run with the permissions     of the PDF viewer by its worker. (CVE-2018-5158)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors and other implementation errors may lead to the execution of arbitrary code or denial of service.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has firefox packages installed that are affected by multiple vulnerabilities:

  - A buffer overflow can occur when rendering canvas     content while adjusting the height and width of the     canvas element dynamically, causing data to be written     outside of the currently computed boundaries. This     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 60, Thunderbird <     52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and     Firefox < 61. (CVE-2018-12359)

  - A use-after-free vulnerability can occur when deleting     an input element during a mutation event handler     triggered by focusing that element. This results in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 60, Thunderbird < 52.9, Firefox     ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12360)

  - An integer overflow can occur during graphics operations     done by the Supplemental Streaming SIMD Extensions 3     (SSSE3) scaler, resulting in a potentially exploitable     crash. This vulnerability affects Thunderbird < 60,     Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR <     52.9, and Firefox < 61. (CVE-2018-12362)

  - A use-after-free vulnerability can occur when script     uses mutation events to move DOM nodes between     documents, resulting in the old document that held the     node being freed but the node still having a pointer     referencing it. This results in a potentially     exploitable crash. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12363)

  - NPAPI plugins, such as Adobe Flash, can send non-simple     cross-origin requests, bypassing CORS by making a same-     origin POST that does a 307 redirect to the target site.
    This allows for a malicious site to engage in cross-site     request forgery (CSRF) attacks. This vulnerability     affects Thunderbird < 60, Thunderbird < 52.9, Firefox     ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12364)

  - A compromised IPC child process can escape the content     sandbox and list the names of arbitrary files on the     file system without user consent or interaction. This     could result in exposure of private local files. This     vulnerability affects Thunderbird < 60, Thunderbird <     52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and     Firefox < 61. (CVE-2018-12365)

  - An invalid grid size during QCMS (color profile)     transformations can result in the out-of-bounds read     interpreted as a float value. This could leak private     data into the output. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-12366)

  - A vulnerability can occur when capturing a media stream     when the media source type is changed as the capture is     occurring. This can result in stream data being cast to     the wrong type causing a potentially exploitable crash.
    This vulnerability affects Thunderbird < 60, Firefox ESR     < 60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-5156)

  - Memory safety bugs present in Firefox 60, Firefox ESR     60, and Firefox ESR 52.8. Some of these bugs showed     evidence of memory corruption and we presume that with     enough effort that some of these could be exploited to     run arbitrary code. This vulnerability affects     Thunderbird < 60, Thunderbird < 52.9, Firefox ESR <     60.1, Firefox ESR < 52.9, and Firefox < 61.
    (CVE-2018-5188)

  - A precision error in Skia in Google Chrome prior to     67.0.3396.62 allowed a remote attacker to perform an out     of bounds memory write via a crafted HTML page.
    (CVE-2018-6126)

  - A use-after-free vulnerability can occur while     enumerating attributes during SVG animations with clip     paths. This results in a potentially exploitable crash.
    This vulnerability affects Thunderbird < 52.8,     Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR <     52.8. (CVE-2018-5154)

  - A use-after-free vulnerability can occur while adjusting     layout during SVG animations with text paths. This     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 52.8, Thunderbird     ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
    (CVE-2018-5155)

  - Same-origin protections for the PDF viewer can be     bypassed, allowing a malicious site to intercept     messages meant for the viewer. This could allow the site     to retrieve PDF files restricted to viewing by an     authenticated user on a third-party website. This     vulnerability affects Firefox ESR < 52.8 and Firefox <     60. (CVE-2018-5157)

  - The PDF viewer does not sufficiently sanitize PostScript     calculator functions, allowing malicious JavaScript to     be injected through a crafted PDF file. This JavaScript     can then be run with the permissions of the PDF viewer     by its worker. This vulnerability affects Firefox ESR <     52.8 and Firefox < 60. (CVE-2018-5158)

  - An integer overflow can occur in the Skia library due to     32-bit integer use in an array without integer overflow     checks, resulting in possible out-of-bounds writes. This     could lead to a potentially exploitable crash     triggerable by web content. This vulnerability affects     Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5159)

  - A buffer overflow was found during UTF8 to Unicode     string conversion within JavaScript with extremely large     amounts of data. This vulnerability requires the use of     a malicious or vulnerable legacy extension in order to     occur. This vulnerability affects Thunderbird ESR <     52.8, Thunderbird < 52.8, and Firefox ESR < 52.8.
    (CVE-2018-5178)

  - Mozilla developers backported selected changes in the     Skia library. These changes correct memory corruption     issues including invalid buffer reads and writes during     graphic operations. This vulnerability affects     Thunderbird ESR < 52.8, Thunderbird < 52.8, and Firefox     ESR < 52.8. (CVE-2018-5183)

  - A use-after-free vulnerability can occur in the     compositor during certain graphics operations when a raw     pointer is used instead of a reference counted one. This     results in a potentially exploitable crash. This     vulnerability affects Firefox ESR < 52.7.3 and Firefox <     59.0.2. (CVE-2018-5148)

  - When entered directly, Reader Mode did not strip the     username and password section of URLs displayed in the     addressbar. This can be used for spoofing the domain of     the current page. This vulnerability affects Firefox <     54. (CVE-2017-7762)

  - Memory safety bugs present in Firefox 61 and Firefox ESR     60.1. Some of these bugs showed evidence of memory     corruption and we presume that with enough effort that     some of these could be exploited to run arbitrary code.
    This vulnerability affects Firefox < 62, Firefox ESR <     60.2, and Thunderbird < 60.2.1. (CVE-2018-12376)

  - A use-after-free vulnerability can occur when refresh     driver timers are refreshed in some circumstances during     shutdown when the timer is deleted while still in use.
    This results in a potentially exploitable crash. This     vulnerability affects Firefox < 62, Firefox ESR < 60.2,     and Thunderbird < 60.2.1. (CVE-2018-12377)

  - A use-after-free vulnerability can occur when an     IndexedDB index is deleted while still in use by     JavaScript code that is providing payload values to be     stored. This results in a potentially exploitable crash.
    This vulnerability affects Firefox < 62, Firefox ESR <     60.2, and Thunderbird < 60.2.1. (CVE-2018-12378)

  - When the Mozilla Updater opens a MAR format file which     contains a very long item filename, an out-of-bounds     write can be triggered, leading to a potentially     exploitable crash. This requires running the Mozilla     Updater manually on the local system with the malicious     MAR file in order to occur. This vulnerability affects     Firefox < 62, Firefox ESR < 60.2, and Thunderbird <     60.2.1. (CVE-2018-12379)

  - If a user saved passwords before Firefox 58 and then     later set a master password, an unencrypted copy of     these passwords is still accessible. This is because the     older stored password file was not deleted when the data     was copied to a new format starting in Firefox 58. The     new master password is added only on the new file. This     could allow the exposure of stored password data outside     of user expectations. This vulnerability affects Firefox     < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
    (CVE-2018-12383)

  - A vulnerability in register allocation in JavaScript can     lead to type confusion, allowing for an arbitrary read     and write. This leads to remote code execution inside     the sandboxed content process when triggered. This     vulnerability affects Firefox ESR < 60.2.2 and Firefox <     62.0.3. (CVE-2018-12386)

  - A vulnerability where the JavaScript JIT compiler     inlines Array.prototype.push with multiple arguments     that results in the stack pointer being off by 8 bytes     after a bailout. This leaks a memory address to the     calling function which can be used as part of an exploit     inside the sandboxed content process. This vulnerability     affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.
    (CVE-2018-12387)

  - Firefox proxy settings can be bypassed by using the     automount feature with autofs to create a mount point on     the local file system. Content can be loaded from this     mounted file system directly using a `file:` URI,     bypassing configured proxy settings. This issue only     affects OS X in default configuration; on Linux systems,     autofs must also be installed for the vulnerability to     occur. (CVE-2017-16541)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox ESR 60.2. Some of these     bugs showed evidence of memory corruption and we presume     that with enough effort that some of these could be     exploited to run arbitrary code. This vulnerability     affects Firefox ESR < 60.3 and Thunderbird < 60.3.
    (CVE-2018-12389)

  - When manipulating user events in nested loops while     opening a document through script, it is possible to     trigger a potentially exploitable crash due to poor     event handling. This vulnerability affects Firefox < 63,     Firefox ESR < 60.3, and Thunderbird < 60.3.
    (CVE-2018-12392)

  - By rewriting the Host: request headers using the     webRequest API, a WebExtension can bypass domain     restrictions through domain fronting. This would allow     access to domains that share a host that are otherwise     restricted. This vulnerability affects Firefox ESR <     60.3 and Firefox < 63. (CVE-2018-12395)

  - A vulnerability where a WebExtension can run content     scripts in disallowed contexts following navigation or     other events. This allows for potential privilege     escalation by the WebExtension on sites where content     scripts should not be run. This vulnerability affects     Firefox ESR < 60.3 and Firefox < 63. (CVE-2018-12396)

  - A WebExtension can request access to local files without     the warning prompt stating that the extension will     Access your data for all websites being displayed to     the user. This allows extensions to run content scripts     in local pages without permission warnings when a local     file is opened. This vulnerability affects Firefox ESR <     60.3 and Firefox < 63. (CVE-2018-12397)

  - A potentially exploitable crash in TransportSecurityInfo     used for SSL can be triggered by data stored in the     local cache in the user profile directory. This issue is     only exploitable in combination with another     vulnerability allowing an attacker to write data into     the local cache or from locally installed malware. This     issue also triggers a non-exploitable startup crash for     users switching between the Nightly and Release versions     of Firefox if the same profile is used. This     vulnerability affects Thunderbird < 60.2.1, Firefox ESR     < 60.2.1, and Firefox < 62.0.2. (CVE-2018-12385)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 62 and Firefox ESR 60.2.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort that some of     these could be exploited to run arbitrary code. This     vulnerability affects Firefox < 63, Firefox ESR < 60.3,     and Thunderbird < 60.3. (CVE-2018-12390)

  - A potential vulnerability was found in 32-bit builds     where an integer overflow during the conversion of     scripts to an internal UTF-16 representation could     result in allocating a buffer too small for the     conversion. This leads to a possible out-of-bounds     write. *Note: 64-bit builds are not vulnerable to this     issue.*. This vulnerability affects Firefox < 63,     Firefox ESR < 60.3, and Thunderbird < 60.3.
    (CVE-2018-12393)

  - Memory safety bugs were reported in Firefox 59, Firefox     ESR 52.7, and Thunderbird 52.7. Some of these bugs     showed evidence of memory corruption and we presume that     with enough effort that some of these could be exploited     to run arbitrary code. This vulnerability affects     Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5150)

  - Sites can bypass security checks on permissions to     install lightweight themes by manipulating the baseURI     property of the theme element. This could allow a     malicious site to install a theme without user     interaction which could contain offensive or     embarrassing images. This vulnerability affects     Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5168)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
