"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-2023:0185 advisory.

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

      CVE-2023-4051:
      A website could have obscured the full screen notification by using the file open dialog. This could
    have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 116,
    Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4053:
      A website could have obscured the full screen notification by using a URL with a scheme handled by an
    external program, such as a mailto URL. This could have led to user confusion and possible spoofing
    attacks. This vulnerability affects Firefox < 116, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4573:
      When receiving rendering data over IPC mStream could have been destroyed when initialized, which could
    have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox <
    117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4574:
      When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks
    could have been created at a time and eventually all simultaneously destroyed as soon as one of the
    callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This
    vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4575:
      When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks
    could have been created at a time and eventually all simultaneously destroyed as soon as one of the
    callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This
    vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4577:
      When UpdateRegExpStatics attempted to access initialStringHeap it could already have been garbage
    collected prior to entering the function, which could potentially have led to an exploitable crash. This
    vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4578:
      When calling JS::CheckRegExpSyntax a Syntax Error could have been set which would end in calling
    convertToRuntimeErrorAndClear. A path in the function could attempt to allocate memory when none is
    available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax
    Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4580:
      Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing
    the leak of sensitive information. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and
    Thunderbird < 115.2.

      CVE-2023-4581:
      Excel .xll add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed
    them to be downloaded without any warning of their potential harm. This vulnerability affects Firefox <
    117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4583:
      When checking if the Browsing Context had been discarded in HttpBaseChannel, if the load group was not
    available then it was assumed to have already been discarded which was not always the case for private
    channels after the private session had ended. This vulnerability affects Firefox < 117, Firefox ESR <
    115.2, and Thunderbird < 115.2.

      CVE-2023-4584:
      Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14,
    and Thunderbird 115.1. 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 < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, and Thunderbird < 115.2.

      CVE-2023-4585:
      Memory safety bugs present in Firefox 116, Firefox ESR 115.1, and Thunderbird 115.1. 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 < 117, Firefox ESR < 115.2, and
    Thunderbird < 115.2.
