Alpine: multiple firefox-esr packages: security update to 78.15.0-r0

high Tenable Cloud Security Plugin ID 404444

Description

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

- During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in
memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,
Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)

- Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 78.15, Thunderbird < 91.2,
Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38500)
