"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0244 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-2616:
    To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead
    of attempt to continue. This vulnerability affects Firefox ESR < 115.9 and Thunderbird < 115.9.

    CVE-2024-2614:
    Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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 < 124, Firefox ESR < 115.9, and
    Thunderbird < 115.9.

    CVE-2024-2612:
    If an attacker could find a way to trigger a particular code path in `SafeRefPtr`, it could have triggered
    a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 124,
    Firefox ESR < 115.9, and Thunderbird < 115.9.

    CVE-2024-2611:
    A missing delay on when pointer lock was used could have allowed a malicious page to trick a user into
    granting permissions. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird <
    115.9.

    CVE-2024-2610:
    Using a markup injection an attacker could have stolen nonce values. This could have been used to bypass
    strict content security policies. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and
    Thunderbird < 115.9.

    CVE-2024-2608:
    `AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding()` and `AppendEncodedCharacters()` could
    have experienced integer overflows, causing underallocation of an output buffer leading to an out of
    bounds write. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.

    CVE-2024-2607:
    Return registers were overwritten which could have allowed an attacker to execute arbitrary code. *Note:*
    This issue only affected Armv7-A systems. Other operating systems are unaffected. This vulnerability
    affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.

    CVE-2024-2605:
    An attacker could have leveraged the Windows Error Reporter to run arbitrary code on the system escaping
    the sandbox. *Note:* This issue only affected Windows operating systems. Other operating systems are
    unaffected. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.

    CVE-2024-0743:
    An unchecked return value in TLS handshake code could have caused a potentially exploitable crash. This
    vulnerability affects Firefox < 122.

    CVE-2023-5388:
    NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could
    potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124,
    Firefox ESR < 115.9, and Thunderbird < 115.9.

    CVE-2024-29944:
    An attacker was able to inject an event handler into a privileged object that would allow arbitrary
    JavaScript execution in the parent process. This vulnerability affects Firefox < 124.0.1 and Firefox ESR <
    115.9.1.
