Rocky Linux 8 : thunderbird (RLSA-2023:1802)

high Nessus Plugin ID 174799


The remote Rocky Linux host is missing one or more security updates.


The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:1802 advisory.

- matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 24.0.0 events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This vulnerability is distinct from GHSA-rfv9-x7hh-xc32 which covers a similar issue. The issue has been patched in matrix-js-sdk 24.0.0 and users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-28427)

- Ribose RNP before 0.16.3 may hang when the input is malformed. (CVE-2023-29479)

- OCSP revocation status of recipient certificates was not checked when sending S/Mime encrypted email, and revoked certificates would be accepted. Thunderbird versions from 68 to 102.9.1 were affected by this bug.

- Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash. (CVE-2023-1945)

- A website could have obscured the fullscreen notification by using a combination of <code></code>, fullscreen requests, <code></code> assignments, and <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks.

- Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash. (CVE-2023-29535)

- An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker- controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.

- When handling the filename directive in the Content-Disposition header, the filename would be truncated if the filename contained a NULL character. This could have led to reflected file download attacks potentially tricking users to install malware. (CVE-2023-29539)

- Thunderbird did not properly handle downloads of files ending in <code>.desktop</code>, which can be interpreted to run attacker-controlled commands. This bug only affects Thunderbird for Linux on certain Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected Linux Distributions. (CVE-2023-29541)

- A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.

- Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.9. 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-2023-29550)

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


Update the affected thunderbird, thunderbird-debuginfo and / or thunderbird-debugsource packages.
