Alpine: mozjs78: security update to 78.13.0-r0

high Tenable Cloud Security Plugin ID 405624

Description

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

 - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly
 considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
 This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
 (CVE-2021-29984)

 - Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. 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 < 78.13, Firefox ESR < 78.13,
 and Firefox < 91. (CVE-2021-29989)
