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 115.5.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-52 advisory.

 - On some systemsdepending on the graphics settings and driversit was possible to force an out-of-bounds read and leak memory data into the images created on the canvas element. (CVE-2023-6204)

 - It was possible to cause the use of a MessagePort after it had already been freed, which could potentially have led to an exploitable crash. (CVE-2023-6205)

 - The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. (CVE-2023-6206)

 - Ownership mismanagement led to a use-after-free in ReadableByteStreams (CVE-2023-6207)

 - When using X11, text selected by the page using the Selection API was erroneously copied into the primary selection, a temporary storage not unlike the clipboard. This bug only affects Thunderbird on X11. Other systems are unaffected. (CVE-2023-6208)

 - Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal /../ part in the path could be used to override the specified host. This could contribute to security problems in web sites. (CVE-2023-6209)

 - Memory safety bugs present in Firefox 119, Firefox 115.4, and Thunderbird 115.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. (CVE-2023-6212)

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

Solution

Upgrade to Mozilla Thunderbird version 115.5.0 or later.
