Alpine: multiple firefox packages: security update to 99.0-r0

high Tenable Cloud Security Plugin ID 404391

Description

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

- regex is an implementation of regular expressions for the Rust language. The regex crate features built-in
mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched
by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This
guarantee is documented and it's considered part of the crate's API. Unfortunately a bug was discovered in
the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing,
and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial
of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted
regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is
include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade
immediately to the latest version of the regex crate. Unfortunately there is no fixed set of problematic
regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability.
Because of this, it us not recommend to deny known problematic regexes. (CVE-2022-24713)

- <code>NSSToken</code> objects were referenced via direct points, and could have been accessed in an unsafe
way on different threads, leading to a use-after-free and potentially exploitable crash. This
vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. (CVE-2022-1097)

- If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to
the parent process, an out of bounds write would have occurred leading to memory corruption and a
potentially exploitable crash. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox
ESR < 91.8. (CVE-2022-28281)

- By using a link with <code>rel="localization"</code> a use-after-free could have been triggered by
destroying an object during JavaScript execution and then referencing the object through a freed pointer,
leading to a potential exploitable crash. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and
Firefox ESR < 91.8. (CVE-2022-28282)
