"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-2023:0315 advisory.

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

      CVE-2023-6204:
      On some systemsdepending on the graphics settings and driversit was possible to force an out-of-
    bounds read and leak memory data into the images created on the canvas element. This vulnerability affects
    Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

      CVE-2023-6205:
      It was possible to cause the use of a MessagePort after it had already been freed, which could
    potentially have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR <
    115.5.0, and Thunderbird < 115.5.

      CVE-2023-6206:
      The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on
    permission prompts. It was possible to use this fact to surprise users by luring them to click where the
    permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR <
    115.5.0, and Thunderbird < 115.5.

      CVE-2023-6207:
      Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects
    Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

      CVE-2023-6208:
      When using X11, text selected by the page using the Selection API was erroneously copied into the
    primary selection, a temporary storage not unlike the clipboard.
      *This bug only affects Firefox on X11. Other systems are unaffected.* This vulnerability affects Firefox
    < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

      CVE-2023-6209:
      Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal /../ part in
    the path could be used to override the specified host. This could contribute to security problems in web
    sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.

      CVE-2023-6212:
      Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and
    Thunderbird < 115.5.
