The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 78.10.1. It is, therefore, affected by a vulnerability as referenced in the mfsa2021-19 advisory.

  - The Maintenance Service granted SERVICESTART access to BUILTIN|Users which, in a domain     network, grants normal remote users access to start or stop the service. This could be used to prevent the     browser update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack     surface in the maintenance service.Note: This issue only affected Windows operating systems older than     Win 10 build 1709. Other operating systems are unaffected. (CVE-2021-29951)

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

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1854-1 advisory.

  - Thunderbird unprotects a secret OpenPGP key prior to using it for a decryption, signing or key import     task. If the task runs into a failure, the secret key may remain in memory in its unprotected state. This     vulnerability affects Thunderbird < 78.8.1. (CVE-2021-29950)

  - The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network,     grants normal remote users access to start or stop the service. This could be used to prevent the browser     update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface     in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10     build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1,     Firefox < 87, and Firefox ESR < 78.10.1. (CVE-2021-29951)

  - OpenPGP secret keys that were imported using Thunderbird version 78.8.1 up to version 78.10.1 were stored     unencrypted on the user's local disk. The master password protection was inactive for those keys. Version     78.10.2 will restore the protection mechanism for newly imported keys, and will automatically protect keys     that had been imported using affected Thunderbird versions. This vulnerability affects Thunderbird <     78.10.2. (CVE-2021-29956)

  - If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an     additional unprotected part, Thunderbird did not indicate that only parts of the message are protected.
    This vulnerability affects Thunderbird < 78.10.2. (CVE-2021-29957)

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

This update for MozillaFirefox fixes the following issues :

Firefox Extended Support Release 78.11.0 ESR (bsc#1186696)

  - CVE-2021-29964: Out of bounds-read when parsing a     `WM_COPYDATA` message

  - CVE-2021-29967: Memory safety bugs fixed in Firefox

This update was imported from the SUSE:SLE-15-SP2:Update update project.

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1884-1 advisory.

  - A locally-installed hostile program could send `WM_COPYDATA` messages that Firefox would process     incorrectly, leading to an out-of-bounds read. *This bug only affects Firefox on Windows. Other operating     systems are unaffected.*. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR <     78.11. (CVE-2021-29964)

  - Mozilla developers 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.
