The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5113 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)

  - 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)

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