The version of Mozilla Thunderbird installed on the remote macOS or Mac OS X host is prior to 52.1. It is, therefore, affected by multiple vulnerabilities :

  - Multiple flaws exist in the Libevent library, within     files evdns.c and evutil.c, due to improper validation     of input when handling IP address strings, empty base     name strings, and DNS packets. An unauthenticated,     remote attacker can exploit these to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2016-10195, CVE-2016-10196, CVE-2016-10197)

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2017-5429, CVE-2017-5430)

  - A use-after-free error exists in input text selection     that allows an unauthenticated, remote attacker to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5432)

  - A use-after-free error exists in the SMIL animation     functions when handling animation elements. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5433)

  - A use-after-free error exists when redirecting focus     handling that allows an unauthenticated, remote attacker     to cause a denial of service condition or the execution     of arbitrary code. (CVE-2017-5434)

  - A use-after-free error exists in design mode     interactions when handling transaction processing in     the editor. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5435)

  - An out-of-bounds write error exists in the Graphite 2     library when handling specially crafted Graphite fonts.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5436)

  - A use-after-free error exists in the nsAutoPtr()     function during XSLT processing due to the result     handler being held by a freed handler. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5438)

  - A use-after-free error exists in the Length() function     in nsTArray when handling template parameters during     XSLT processing. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5439)

  - A use-after-free error exists in the txExecutionState     destructor when processing XSLT content. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5440)

  - A use-after-free error exists when holding a selection     during scroll events. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2017-5441)

  - A use-after-free error exists when changing styles in     DOM elements that allows an unauthenticated, remote     attacker to cause a denial of service condition or the     execution of arbitrary code. (CVE-2017-5442)

  - An out-of-bounds write error exists while decoding     improperly formed BinHex format archives that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-5443)

  - A buffer overflow condition exists while parsing     application/http-index-format format content due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this, via     improperly formatted data, to disclose out-of-bounds     memory content. (CVE-2017-5444)

  - A flaw exists in nsDirIndexParser.cpp when parsing     application/http-index-format format content in which     uninitialized values are used to create an array. An     unauthenticated, remote attacker can exploit this to     disclose memory contents. (CVE-2017-5445)

  - An out-of-bounds read error exists when handling HTTP/2     DATA connections to a server that sends DATA frames with     incorrect content. An unauthenticated, remote attacker     can exploit to cause a denial of service condition or     the disclosure of memory contents. (CVE-2017-5446)

  - An out-of-bounds read error exists when processing glyph     widths during text layout. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition or the disclosure of memory contents.
    (CVE-2017-5447)

  - A flaw exists when handling bidirectional Unicode text     in conjunction with CSS animations that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution or arbitrary code.
    (CVE-2017-5449)

  - A flaw exists in the handling of specially crafted     'onblur' events. An unauthenticated, remote attacker can     exploit this, via a specially crafted event, to spoof     the address bar, making the loaded site appear to be     different from the one actually loaded. (CVE-2017-5451)

  - A flaw exists in the FileSystemSecurity::Forget()     function within file FileSystemSecurity.cpp when using     the File Picker due to improper sanitization of input     containing path traversal sequences. An unauthenticated,     remote attacker can exploit this to bypass file system     access protections in the sandbox and read arbitrary     files on the local file system. (CVE-2017-5454)

  - A buffer overflow condition exists in WebGL when     handling web content due to improper validation of     certain input. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5459)

  - A use-after-free error exists in frame selection when     handling a specially crafted combination of script     content and key presses by the user. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-5460)

  - An out-of-bounds write error exists in the Network     Security Services (NSS) library during Base64 decoding     operations due to insufficient memory being allocated to     a buffer. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5461)

  - A flaw exists in the Network Security Services (NSS)     library during DRBG number generation due to the     internal state V not correctly carrying bits over. An     unauthenticated, remote attacker can exploit this to     potentially cause predictable random number generation.
    (CVE-2017-5462)

  - A flaw exists when making changes to DOM content in the     accessibility tree due to improper validation of certain     input, which can lead to the DOM tree becoming out of     sync with the accessibility tree. An unauthenticated,     remote attacker can exploit this to corrupt memory,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2017-5464)

  - An out-of-bounds read error exists in ConvolvePixel when     processing SVG content, which allows for otherwise     inaccessible memory being copied into SVG graphic     content. An unauthenticated, remote attacker can exploit     this to disclose memory contents or cause a denial of     service condition. (CVE-2017-5465)

  - A cross-site scripting (XSS) vulnerability exists due to     improper handling of data:text/html URL redirects when     a reload is triggered, which causes the reloaded     data:text/html page to have its origin set incorrectly.
    An unauthenticated, remote attacker can exploit this,     via a specially crafted request, to execute arbitrary     script code in a user's browser session. (CVE-2017-5466)

  - A memory corruption issue exists when rendering Skia     content outside of the bounds of a clipping region due     to improper validation of certain input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5467)

  - A buffer overflow condition exists in the FLEX generated     code due to improper validation of user-supplied input.
    An unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-5469)
