"The remote NewStart CGSL host, running version MAIN 6.06, has gstreamer1-plugins-base packages installed that are
affected by a vulnerability:

  - 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. (CVE-2024-47615)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
