Multiple security issues were discovered in Thunderbird, which could result in the execution of arbitrary code or information disclosure

Debian follows the Thunderbird upstream releases. Support for the 140.x series has ended, so starting with this update we're now following the 153.x series.

For Debian 12 bookworm, these problems have been fixed in version 1:153.5.1esr-1~deb12u1.

We recommend that you upgrade your thunderbird packages.

For the detailed security status of thunderbird please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/thunderbird

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the thunderbird packages.
