The version of Firefox installed on the remote Windows host is prior to 63.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-26 advisory.

  - 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. (CVE-2018-12392)

  - During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in     violation of security policies. Because the problem is in the underlying Android service, this issue is     addressed by treating all HLS streams as cross-origin and opaque to access.  Note: this issue only affects     Firefox for Android. Desktop versions of Firefox are unaffected. (CVE-2018-12391)

  - 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. (CVE-2018-12393)

  - By rewriting the <code>Host</code> request headers using the <code>webRequest</code> API, a WebExtension     can bypass domain restrictions through domain fronting. This would allow access to domains that share a     host that are otherwise restricted. (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. (CVE-2018-12396)

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

Bug Fix(es) :

* Previously, passwords saved in the Firefox browser and encrypted by a master password were erased when Firefox was exited. This update ensures that NSS files used to decrypt stored login data are handled correctly. As a result, the affected passwords are no longer lost after restarting Firefox. (BZ#1638082)
