"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-2023:0052 advisory.

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

      CVE-2023-29548:
      A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
      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-2023-29550:
      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-2023-29535:
      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-2023-29533:
      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-2023-29541:
      Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run
    attacker-controlled commands.
      CVE-2023-1945:
      Unexpected data returned from the Safe Browsing API could have led to memory corruption and a
    potentially exploitable crash.
