The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Mozilla NSS: Errors in mp_div and mp_exptmod cryptographic functions (CVE-2016-1938)

  - SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32) (CVE-2016-2183)

  - The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer,     Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained     initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a     blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses     (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a     BEAST attack. (CVE-2011-3389)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Multiple security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, buffer overflows and other implementation errors may lead to the execution of arbitrary code or bypass of the same-origin policy. Also, a man-in-the-middle attack in the addon update mechanism has been fixed.

The remote host is affected by the vulnerability described in GLSA-201701-46 (Mozilla Network Security Service (NSS): Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in NSS. Please review the       CVE identifiers and technical papers referenced below for details.
  Impact :

    Remote attackers could conduct man-in-the-middle attacks, obtain access       to private key information, or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The version of Mozilla Firefox installed on the remote Windows host is prior to 50.0. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

This update to Mozilla Firefox 50.0 fixes a number of security issues.

The following vulnerabilities were fixed in Mozilla Firefox (MFSA 2016-89) :

  - CVE-2016-5296: Heap-buffer-overflow WRITE in     rasterize_edges_1 (bmo#1292443)

  - font warning messages would flood console, now using     fontconfig configuration from firefox-fontconfig instead     of the system one (bsc#1000751)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Versions of Mozilla Firefox ESR earlier than 45.5 are unpatched for the following vulnerabilities :

 - An overflow condition exists in the 'RASTERIZE_EDGES()' function in 'gfx/cairo/libpixman/src/pixman-edge-imp.h'. The issue is triggered as certain input is not properly validated when handling SVG content. This may allow a context-dependent attacker to cause a heap-based overflow, potentially allowing the execution of arbitrary code.
 - A flaw exists that is triggered when the Mozilla Updater is run with the updater's log file in the working directory pointing to a hardlink. This may allow a local attacker to append data to an arbitrary local file.
 - A flaw exists in the Mozilla Updater that is triggered as it may select an arbitrary target working directory to output files from the update process. No further details have been provided by the vendor.
 - A flaw exists that is triggered when length checking JavaScript arguments. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists that is triggered as add-on update IDs are not properly validated. This may allow an attacker with the ability to intercept network traffic '(e.g'. MitM, DNS cache poisoning) to provide malicious add-on updates.

 - A flaw exists in 'toolkit/components/extensions/ExtensionContent.jsm' that is triggered as WebExtensions may inappropriately access the mozAddonManager API. This may allow a context-dependent attacker to use a specially crafted extension to install further extensions without a user's permission.
 - A flaw exists in 'dom/canvas/CanvasRenderingContext2D.cpp' that is triggered by the use of the feDisplacementMap filter on images that are loaded cross-origin. This may allow a context-dependent attacker to conduct a timing attack and have an unspecified impact.
 - A flaw exists in the 'nsBaseChannel::Redirect()' function in 'netwerk/base/nsBaseChannel.cpp'. The issue is triggered as local shortcut files may be used to bypass the same-origin policy and load local content from the disk.
 - A flaw exists in the 'ProcessSoftwareUpdateCommand()' function in 'toolkit/components/maintenanceservice/workmonitor.cpp', as it may copy 'updater.exe' from untrusted directories. This may allow a local attacker to read files with SYSTEM privileges.
 - A flaw exists that is triggered when a page load is disrupted. This may result in the previous page's favicon and SSL indicator persisting, potentially misleading a user about the URL of the page being visited.
 - A flaw exists that is triggered when a previously installed application defines the same signature-level permissions as Firefox. This may allow a local attacker to intercept and disclose AuthTokens intended to be sent to Firefox.
 - A flaw exists that is triggered when a previously installed application defines the same signature-level permissions as Firefox. This may allow a local attacker to intercept and disclose API keys intended to be sent to Firefox.
 - A flaw exists in 'mobile/android/base/java/org/mozilla/gecko/PrivateTab.java' that is triggered, as browsing metadata from private browsing may persist in the 'browser.db' and 'browser.db'-wal files within a Firefox profile. This may potentially allow a physically present attacker to disclose information about private browsing.
 - A flaw exists in 'dom/bindings/Codegen.py' that is triggered when loading pages in a sidebar via a bookmark. This may allow the page to reference a privileged chrome window, violating the same-origin policy and engaging in limited JavaScript operations.
 - A flaw exists that is triggered as the 'windows.create' schema doesn't specify "format": "relativeUrl". This may allow a context-dependent attacker to escape the WebExtension sandbox.
 - An unspecified flaw exists in 'divSpoiler' that may allow an attacker to conduct a side-channel attack. No further details have been provided by the vendor.
 - A flaw exists that is triggered as the "select" dropdown menu may potentially cover location bar content, allowing a context-dependent attacker to spoof the location bar.
 - An integer overflow condition exists in the 'XML_Parse()' function in 'parser/expat/lib/xmlparse.c'. The issue is triggered as certain input is not properly validated when parsing XML content. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists in the 'nsCSPHostSrc::permits()' function in 'dom/security/nsCSPUtils.cpp' that is triggered when the Content Security Policy (CSP) is combined with HTTP to HTTPS redirection. This may potentially allow a context-dependent attacker to enumerate the existence of a known site in a user's browser history.
 - An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'EventListenerManager::GetListenerInfo()' function in 'dom/events/EventListenerManager.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
