Mozilla Thunderbird < 144.0

medium Nessus Plugin ID 270355

Language:

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 144.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-84 advisory.

 - A malicious page could have used the type attribute of an OBJECT tag to override the default browser behavior when encountering a web resource served without a content-type. This could have contributed to an XSS on a site that unsafely serves files without a content-type header. (CVE-2025-11712)

 - Use-after-free in MediaTrackGraphImpl::GetInstance() (CVE-2025-11708)

 - A compromised web process was able to trigger out of bounds reads and writes in a more privileged process using manipulated WebGL textures. (CVE-2025-11709)

 - A compromised web process using malicious IPC messages could have caused the privileged browser process to reveal blocks of its memory to the compromised process. (CVE-2025-11710)

 - There was a way to change the value of JavaScript Object properties that were supposed to be non- writeable. (CVE-2025-11711)

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 144.0 or later.
