Alpine: multiple firefox packages: security update to 81.0-r0

high Tenable Cloud Security Plugin ID 404372

Description

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

- When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in
a potential use-after-free. This occurs because the function
APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This
vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15678)

- Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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 < 81, Thunderbird < 78.3, and
Firefox ESR < 78.3. (CVE-2020-15673)

- Mozilla developers reported memory safety bugs present in Firefox 80. 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 < 81. (CVE-2020-15674)

- When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a
potentially exploitable crash. This vulnerability affects Firefox < 81. (CVE-2020-15675)

- Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove,
resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable
element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
(CVE-2020-15676)
