"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-2024:0353 advisory.

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

    CVE-2023-2617:
    A vulnerability classified as problematic was found in OpenCV wechat_qrcode Module up to 4.7.0. Affected
    by this vulnerability is the function DecodedBitStreamParser::decodeByteSegment of the file
    qrcode/decoder/decoded_bit_stream_parser.cpp. The manipulation leads to null pointer dereference. The
    attack can be launched remotely. The exploit has been disclosed to the public and may be used. It is
    recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is
    VDB-228547.

    CVE-2023-2618:
    A vulnerability, which was classified as problematic, has been found in OpenCV wechat_qrcode Module up to
    4.7.0. Affected by this issue is the function DecodedBitStreamParser::decodeHanziSegment of the file
    qrcode/decoder/decoded_bit_stream_parser.cpp. The manipulation leads to memory leak. The attack may be
    launched remotely. The name of the patch is 2b62ff6181163eea029ed1cab11363b4996e9cd6. It is recommended to
    apply a patch to fix this issue. The identifier of this vulnerability is VDB-228548.

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.");
