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-2024:0246 advisory.

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

    CVE-2024-2609:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The permission prompt input delay could expire while the window is not in focus. This makes it vulnerable     to clickjacking by malicious websites.

    CVE-2024-3302:
    The Mozilla Foundation Security Advisory describes this flaw as:

    There was no limit to the number of HTTP/2 CONTINUATION frames that would be processed. A server could     abuse this to create an Out of Memory condition in the browser.

    CVE-2024-3852:
    The Mozilla Foundation Security Advisory describes this flaw as:

    GetBoundName could return the wrong version of an object when JIT optimizations were applied.

    CVE-2024-3854:
    The Mozilla Foundation Security Advisory describes this flaw as:

    In some code patterns the JIT incorrectly optimized switch statements and generated code with out-of-     bounds-reads.

    CVE-2024-3857:
    The Mozilla Foundation Security Advisory describes this flaw as:

    The JIT created incorrect code for arguments in certain cases. This led to potential use-after-free     crashes during garbage collection.

    CVE-2024-3859:
    The Mozilla Foundation Security Advisory describes this flaw as:

    On 32-bit versions there were integer-overflows that led to an out-of-bounds-read that potentially could     be triggered by a malformed OpenType font.

    CVE-2024-3861:
    The Mozilla Foundation Security Advisory describes this flaw as:

    If an AlignedBuffer were assigned to itself, the subsequent self-move could result in an incorrect     reference count and later use-after-free.

    CVE-2024-3864:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Memory safety bug present in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug showed     evidence of memory corruption and we presume that with enough effort this could have been exploited to run     arbitrary code.
