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-2024:0006 advisory.

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

    CVE-2023-6856:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems     with the Mesa VM driver.  This issue could allow an attacker to perform remote code execution and sandbox     escape.

    CVE-2023-6857:
    The Mozilla Foundation Security Advisory describes this flaw as:

    When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller     than necessary.

    *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is     unaffected.*

    CVE-2023-6858:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling.

    CVE-2023-6859:
    The Mozilla Foundation Security Advisory describes this flaw as:

    A use-after-free condition affected TLS socket creation when under memory pressure.

    CVE-2023-6860:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The `VideoBridge` allowed any content process to use textures produced by remote decoders.  This could be     abused to escape the sandbox.

    CVE-2023-6861:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless     mode.

    CVE-2023-6862:
    The Mozilla Foundation Security Advisory describes this flaw as:

    A use-after-free was identified in the `nsDNSService::Init`.  This issue appears to manifest rarely during     start-up.

    CVE-2023-6863:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The `ShutdownObserver()` was susceptible to potentially undefined behavior due to its reliance on a     dynamic type that lacked a virtual destructor.

    CVE-2023-6864:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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-2023-50761:
    The Mozilla Foundation Security Advisory: The signature of a digitally signed S/MIME email message may     optionally specify the signature creation date and time. If present, Thunderbird did not compare the     signature creation date with the message date and time, and displayed a valid signature despite a date or     time mismatch. This could be used to give recipients the impression that a message was sent at a different     date or time.

    CVE-2023-50762:
    The Mozilla Foundation Security Advisory: When processing a PGP/MIME payload that contains digitally     signed text, the first paragraph of the text was never shown to the user. This is because the text was     interpreted as a MIME message and the first paragraph was always treated as an email header section. A     digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an     email message.
