The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 91.6.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-09 advisory.

  • Removing an XSLT parameter during processing could have lead to an exploitable use-after-free. We have had reports of attacks in the wild abusing this flaw. (CVE-2022-26485)

  • An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox escape. We have had reports of attacks in the wild abusing this flaw. (CVE-2022-26486)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
