Amazon Linux 2 : thunderbird (ALAS-2021-1720)

high Nessus Plugin ID 154912

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of thunderbird installed on the remote host is prior to 78.14.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1720 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)

- Mozilla developers reported memory safety bugs present in Thunderbird 78.13.0. 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 Thunderbird < 91.1 and Firefox ESR < 91.1.
(CVE-2021-38495)

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

Solution

Run 'yum update thunderbird' to update your system.
