The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-1806 advisory.

  - Certain malformed OpenPGP messages could trigger incorrect parsing of PKESK/SKESK packets due to a bug in     the Ribose RNP library used by Thunderbird up to version 102.9.1, which would cause the Thunderbird user     interface to hang. The issue was discovered using Google's oss-fuzz.  (CVE-2023-29479)

  - 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.
    (CVE-2023-29536)

  - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
    (CVE-2023-29548)

  - 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.
    (CVE-2023-0547)

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

  - 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)

  - 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 website could have obscured the fullscreen notification by using a combination of     <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and     <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks.
    (CVE-2023-29533)

  - 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)

  - 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)

  - 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.

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2023:1787 advisory.

    (CVE-2023-1945)

  - There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode()     function and loop through to free best.bw and assign best = trial pointer. The second loop will then     return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the     AddressSanitizer will attempt a double free.
