The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 78.11. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2021-24 advisory.

  • A locally-installed hostile program could send WMCOPYDATA messages that Firefox would processing incorrectly, leading to an out-of-bounds read. This bug only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2021-29964)

  • Mozilla developers Gabriele Svelto, Anny Gakhokidze, Alexandru Michis, Christian Holler reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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-2021-29967)

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