"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1146 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2024-47538:
    GStreamer is a library for constructing graphs of media-handling components. A stack-buffer overflow has
    been detected in the vorbis_handle_identification_packet function within gstvorbisdec.c. The position
    array is a stack-allocated buffer of size 64. If vd->vi.channels exceeds 64, the for loop will write
    beyond the boundaries of the position array. The value written will always be
    GST_AUDIO_CHANNEL_POSITION_NONE. This vulnerability allows someone to overwrite the EIP address allocated
    in the stack. Additionally, this bug can overwrite the GstAudioInfo info structure. This vulnerability is
    fixed in 1.24.10.

    CVE-2024-47607:
    GStreamer is a library for constructing graphs of media-handling components.  stack-buffer overflow has
    been detected in the gst_opus_dec_parse_header function within gstopusdec.c'. The pos array is a stack-
    allocated buffer of size 64. If n_channels exceeds 64, the for loop will write beyond the boundaries of
    the pos array. The value written will always be GST_AUDIO_CHANNEL_POSITION_NONE. This bug allows to
    overwrite the EIP address allocated in the stack. This vulnerability is fixed in 1.24.10.

    CVE-2024-47615:
    GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been
    detected in the function gst_parse_vorbis_setup_packet within vorbis_parse.c. The integer size is read
    from the input file without proper validation. As a result, size can exceed the fixed size of the
    pad->vorbis_mode_sizes array (which size is 256). When this happens, the for loop overwrites the entire
    pad structure with 0s and 1s, affecting adjacent memory as well. This OOB-write can overwrite up to 380
    bytes of memory beyond the boundaries of the pad->vorbis_mode_sizes array. This vulnerability is fixed in
    1.24.10.
