Description

The version of Thunderbird 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 mfsa2021-26 advisory.

  • A locally-installed hostile program could send WMCOPYDATA messages that Thunderbird would processing incorrectly, leading to an out-of-bounds read. This bug only affects Thunderbird 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 Thunderbird 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.
