Alpine: multiple firefox-esr packages: security update to 78.3.0-r0

high Tenable Cloud Security Plugin ID 404446

Description

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

- 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)

- 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)

- By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site
displayed in the download file dialog to show the original site (the one suffering from the open redirect)
rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81,
Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15677)

- 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)
