A same-origin policy violation allowing the theft of cross-origin URL entries when using a meta http-equiv="refresh" on a page to cause a redirection to another site using performance.getEntries(). This is a same-origin policy violation and could allow for data theft. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 60.2.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-25 advisory.

  - 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.
    (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.
    (CVE-2018-12378)

  - A same-origin policy violation allowing the theft of     cross-origin URL entries when using a <meta>     meta http-equiv=refresh on a page to cause a     redirection to another site using     performance.getEntries(). This is a same-     origin policy violation and could allow for data theft.
    (CVE-2018-18499)

  - 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. (CVE-2018-12379)

  - Browser 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. *Note:
    this issue only affects OS X in default configurations.
    On Linux systems, autofs must be installed for the     vulnerability to occur and Windows is not affected.*     (CVE-2017-16541)

  - 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. (CVE-2018-12385)

  - 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. (CVE-2018-12383)

  - Mozilla developers and community members Alex Gaynor,     Boris Zbarsky, Christoph Diehl, Christian Holler, Jason     Kratzer, Jed Davis, Tyson Smith, Bogdan Tara, Karl     Tomlinson, Mats Palmgren, Nika Layzell, Ted Campbell,     and Andrei Cristian Petcu reported 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. (CVE-2018-12376)

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

The version of Mozilla Firefox installed on the remote macOS host is prior to 62. It is, therefore, affected by multiple vulnerabilities as noted in Mozilla Firefox stable channel update release notes for 2018/09/05. Please refer to the release notes for additional information. Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.
