"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-2024:0579 advisory.

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

    CVE-2024-31744:
    In Jasper 4.2.2, the jpc_streamlist_remove function in src/libjasper/jpc/jpc_dec.c:2407 has an assertion
    failure vulnerability, allowing attackers to cause a denial of service attack through a specific image
    file.

    CVE-2023-51257:
    An invalid memory write issue in Jasper-Software Jasper v.4.1.1 and before allows a local attacker to
    execute arbitrary code.

    CVE-2015-8751:
    Integer overflow in the jas_matrix_create function in JasPer allows context-dependent attackers to have
    unspecified impact via a crafted JPEG 2000 image, related to integer multiplication for memory allocation.

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.");
