Synopsis

A mail client installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to Mozilla Thunderbird version 60.2.1 or later.
