Alpine: thunderbird: security update to 91.5.0-r0

critical Tenable Cloud Security Plugin ID 426118

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson
Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR
91.4. 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. This vulnerability affects Firefox ESR < 91.5,
Firefox < 96, and Thunderbird < 91.5. (CVE-2022-22751)

- It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This
vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2021-4140)

- Constructing audio sinks could have lead to a race condition when playing audio files and closing windows.
This could have lead to a use-after-free causing a potentially exploitable crash. This vulnerability
affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2022-22737)

- Applying a CSS filter effect could have accessed out of bounds memory. This could have lead to a heap-
buffer-overflow causing a potentially exploitable crash. This vulnerability affects Firefox ESR < 91.5,
Firefox < 96, and Thunderbird < 91.5. (CVE-2022-22738)

- Malicious websites could have tricked users into accepting launching a program to handle an external URL
protocol. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5.
(CVE-2022-22739)
