GLSA-202209-27 : Mozilla Firefox: Multiple Vulnerabilities

high Nessus Plugin ID 165630

Description

The remote host is affected by the vulnerability described in GLSA-202209-27 (Mozilla Firefox: Multiple Vulnerabilities)

 - When injecting an HTML base element, some requests would ignore the CSP's base-uri settings and accept the injected element's base instead. (CVE-2022-40956)

 - Inconsistent data in instruction and data cache when creating wasm code could lead to a potentially exploitable crash. This bug only affects Firefox on ARM64 platforms. (CVE-2022-40957)

 - By injecting a cookie with certain special characters, an attacker on a shared subdomain which is not a secure context could set and thus overwrite cookies from a secure context, leading to session fixation and other attacks. (CVE-2022-40958)

 - During iframe navigation, certain pages did not have their FeaturePolicy fully initialized leading to a bypass that leaked device permissions into untrusted subdocuments. (CVE-2022-40959)

 - Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after- free causing a potentially exploitable crash. (CVE-2022-40960)

 - Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 104 and Firefox ESR 102.2. 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. (CVE-2022-40962)

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