Debian DSA-4973-1 : thunderbird - security update

high Nessus Plugin ID 153512

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 / 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-4973 advisory.

 - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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. This vulnerability affects Firefox ESR < 78.14, Thunderbird < 78.14, and Firefox < 92. (CVE-2021-38493)

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

Solution

Upgrade the thunderbird packages.

For the stable distribution (bullseye), this problem has been fixed in version 1
