"The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0059 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

      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-2023-1945:
      Unexpected data returned from the Safe Browsing API could have led to memory corruption and a
    potentially exploitable crash.
      CVE-2023-1999:
      A double-free in libwebp could have led to memory corruption and a potentially exploitable crash.
      CVE-2023-28427:
      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-2023-29479:
      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-2023-29533:
      A website could have obscured the fullscreen notification by using a combination of window.open,
    fullscreen requests, window.name assignments, and setInterval calls. This could have led to user confusion
    and possible spoofing attacks.
      CVE-2023-29535:
      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-2023-29536:
      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-2023-29539:
      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-2023-29541:
      Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run
    attacker-controlled commands.
      CVE-2023-29548:
      A wrong Lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
      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.
