Amazon Linux 2 : thunderbird (ALAS-2022-1789)

high Nessus Plugin ID 160257

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of thunderbird installed on the remote host is prior to 91.8.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1789 advisory.

- 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)

- After a VR Process is destroyed, a reference to it may have been retained and used, leading to a use- after-free and potentially exploitable crash. This vulnerability affects Thunderbird < 91.8 and Firefox ESR < 91.8. (CVE-2022-1196)

- When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non- revoked. Revocation statements that used another revocation reason, or that didn't specify a revocation reason, were unaffected. This vulnerability affects Thunderbird < 91.8. (CVE-2022-1197)

- 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
