The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:1786 advisory.

  - 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>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)

  - 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)

  - 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.
    (CVE-2023-29548)

  - 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 version of firefox installed on the remote host is prior to 102.10.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-006 advisory.

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

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.
    (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. (CVE-2023-1999)

  - 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.

An update of the mozjs package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0054 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2023-1945:
      Unexpected data returned from the Safe Browsing API could have led to memory corruption and a     potentially exploitable crash.
      CVE-2023-28427:
      Thunderbird users who use the Matrix chat protocol were vulnerable to a denial-of-service attack.
      CVE-2023-29541:
      Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run     attacker-controlled commands.
      CVE-2023-29550:
      Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team     reported memory safety bugs present in Firefox 111 and Firefox ESR 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-2023-29479:
      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-2023-0547:
      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-2023-29548:
      A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 102.10. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-14 advisory.

  - Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team     reported memory safety bugs present in Firefox 111 and Firefox ESR 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)

  - A newline in a filename could have been used to bypass the file extension security mechanisms that replace     malicious file extensions such as .lnk  with .download. This could have led to accidental execution of     malicious code. This bug only affects Firefox on Windows. Other versions of Firefox are unaffected.
    (CVE-2023-29542)

  - An attacker could have caused an out of bounds memory access using WebGL APIs, leading to memory     corruption and a potentially exploitable crash. This bug only affects Firefox for macOS. Other operating     systems are unaffected. (CVE-2023-29531)

  - A local attacker can trick the Mozilla Maintenance Service into applying an unsigned update file by     pointing the service at an update file on a malicious SMB server. The update file can be replaced after     the signature check, before the use, because the write-lock requested by the service does not work on a     SMB server. Note: This attack requires local system access and only affects Windows. Other operating     systems are not affected. (CVE-2023-29532)

  - 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)
