"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-2024:0089 advisory.

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

    CVE-2024-1546:
    The Mozilla Foundation Security Advisory describes this flaw as:

    When storing and re-accessing data on a networking channel, the length of buffers may have been confused,
    resulting in an out-of-bounds memory read.

    CVE-2024-1547:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Through a series of API calls and redirects, an attacker-controlled alert dialog could have been displayed
    on another website (with the victim website's URL shown).

    CVE-2024-1548:
    The Mozilla Foundation Security Advisory describes this flaw as:

    A website could have obscured the fullscreen notification by using a dropdown select input element. This
    could have led to user confusion and possible spoofing attacks.

    CVE-2024-1549:
    The Mozilla Foundation Security Advisory describes this flaw as:

    If a website set a large custom cursor, portions of the cursor could have overlapped with the permission
    dialog, potentially resulting in user confusion and unexpected granted permissions.

    CVE-2024-1550:
    The Mozilla Foundation Security Advisory describes this flaw as:

    A malicious website could have used a combination of exiting fullscreen mode and `requestPointerLock` to
    cause the user's mouse to be re-positioned unexpectedly, which could have led to user confusion and
    inadvertently granting permissions they did not intend to grant.

    CVE-2024-1551:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker
    could control the Content-Type response header, as well as control part of the response body, they could
    inject Set-Cookie response headers that would have been honored by the browser.

    CVE-2024-1552:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Incorrect code generation could have led to unexpected numeric conversions and potential undefined
    behavior. This issue only affects 32-bit ARM devices.

    CVE-2024-1553:
    The Mozilla Foundation Security Advisory describes this flaw as:

    Memory safety bugs present in Firefox 122, Firefox ESR 115.7, and Thunderbird 115.7. 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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
