Alpine: multiple firefox packages: security update to 84.0.1-r0

critical Tenable Cloud Security Plugin ID 404376

Description

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

- The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must
ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted
in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects
Firefox < 84. (CVE-2020-26972)

- Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain
potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

- Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow
on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <
78.6. (CVE-2020-26971)

- Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This
could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,
and Firefox ESR < 78.6. (CVE-2020-26973)
