The version of Firefox ESR installed on the remote Windows host is prior to 52.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-16 advisory.

  - A number of security vulnerabilities in the Graphite 2 library including out-of-bounds reads, buffer     overflow reads and writes, and the use of uninitialized memory. These issues were addressed in Graphite 2     version 1.3.10. (CVE-2017-7778)

  - A use-after-free vulnerability with the frameloader during tree reconstruction while regenerating CSS     layout when attempting to use a node in the tree that no longer exists. This results in a potentially     exploitable crash. (CVE-2017-5472)

  - A use-after-free vulnerability when using an incorrect URL during the reloading of a docshell. This     results in a potentially exploitable crash. (CVE-2017-7749)

  - A use-after-free vulnerability during video control operations when a <code><track></code> element     holds a reference to an older window if that window has been replaced in the DOM. This results in a     potentially exploitable crash. (CVE-2017-7750)

  - A use-after-free vulnerability with content viewer listeners that results in a potentially exploitable     crash. (CVE-2017-7751)

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

The version of Mozilla Firefox ESR installed on the remote Windows host is prior to 52.2. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code by convincing a user to visit a specially crafted     website. (CVE-2017-5470)

  - A use-after-free error exists in the EndUpdate()     function in nsCSSFrameConstructor.cpp that is triggered     when reconstructing trees during regeneration of CSS     layouts. An unauthenticated, remote attacker can exploit     this, by convincing a user to visit a specially crafted     website, to cause a denial of service condition or the     execution of arbitrary code. (CVE-2017-5472)

  - A use-after-free error exists in the Reload() function     in nsDocShell.cpp that is triggered when using an     incorrect URL during the reload of a docshell. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7749)

  - A use-after-free error exists in the Hide() function in     nsDocumentViewer.cpp that is triggered when handling     track elements. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-7750)

  - A use-after-free error exists in the nsDocumentViewer     class in nsDocumentViewer.cpp that is triggered when     handling content viewer listeners. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-7751)

  - A use-after-free error exists that is triggered when     handling events while specific user interaction occurs     with the input method editor (IME). An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-7752)

  - An out-of-bounds read error exists in the IsComplete()     function in WebGLTexture.cpp that is triggered when     handling textures. An unauthenticated, remote attacker     can exploit this to disclose memory contents.
    (CVE-2017-7754)

  - A privilege escalation vulnerability exists due to     improper loading of dynamic-link library (DLL) files. A     local attacker can exploit this, via a specially crafted     DLL file in the installation path, to inject and execute     arbitrary code. (CVE-2017-7755)

  - A use-after-free error exists in the SetRequestHead()     function in XMLHttpRequestMainThread.cpp that is     triggered when logging XML HTTP Requests (XHR). An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7756)

  - A use-after-free error exists in ActorsParent.cpp due to     improper handling of objects in memory. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7757)

  - An out-of-bounds read error exists in the     AppendAudioSegment() function in TrackEncoder.cpp that     is triggered when the number of channels in an audio     stream changes while the Opus encoder is in use. An     unauthenticated, remote attacker can exploit this to     disclose sensitive information. (CVE-2017-7758)

  - A flaw exists in the NS_main() function in updater.cpp     due to improper validation of input when handling     callback file path parameters. A local attacker can     exploit this to manipulate files in the installation     directory. (CVE-2017-7760)

  - A flaw exists in the Maintenance Service helper.exe     application that is triggered as permissions for a     temporary directory are set to writable by     non-privileged users. A local attacker can exploit this     to delete arbitrary files on the system. (CVE-2017-7761)

  - A flaw exists in the isLabelSafe() function in     nsIDNService.cpp that is triggered when handling     characters from different unicode blocks. An     unauthenticated, remote attacker can exploit this, via a     specially crafted IDN domain, to spoof a valid URL and     conduct phishing attacks. (CVE-2017-7764)

  - A flaw exists that is triggered due to improper parsing     of long filenames when handling downloaded files. An     unauthenticated, remote attacker can exploit this to     cause a file to be downloaded without the     'mark-of-the-web' applied, resulting in security     warnings for executables not being displayed.
    (CVE-2017-7765)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when handling paths for the 'patch',     'install', and 'working' directories. A local attacker     can exploit this to execute arbitrary code with elevated     privileges. (CVE-2017-7766)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when being invoked using the Mozilla Windows     Updater. A local attacker can exploit this to overwrite     arbitrary files with random data. (CVE-2017-7767)

  - A flaw exists in the IsStatusApplying() function in     workmonitor.cpp that is triggered when logging the     update status. A local attacker can exploit this to read     32 bytes of arbitrary files. (CVE-2017-7768)

  - Multiple integer overflow conditions exist in the     Graphite component in the decompress() function in     Decompressor.cpp due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2017-7772,     CVE-2017-7773, CVE-2017-7778)

  - An out-of-bounds read error exists in the Graphite     component in the readGraphite() function in Silf.cpp. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose memory     contents. (CVE-2017-7774)

  - An out-of-bounds read error exists in the Graphite     component in getClassGlyph() function in Silf.cpp due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2017-7776)

  - A flaw exists in the Graphite component in the     read_glyph() function in GlyphCache.cpp related to use     of uninitialized memory. An unauthenticated, remote     attacker can exploit this to have an unspecified impact.
    (CVE-2017-7777)
