"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-2024:0164 advisory.

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

    CVE-2022-1122:
    A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input
    directory with a large number of files. When it fails to allocate a buffer to store the filenames of the
    input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial
    of service.

    CVE-2021-3575:
    A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing
    a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the
    application compiled against openjpeg.

    CVE-2021-29338:
    Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of
    Service (DoS). This occurs when the attacker uses the command line option -ImgDir on a directory that
    contains 1048576 files.

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.");
