"The remote NewStart CGSL host, running version MAIN 7.02, has gstreamer1-plugins-base packages installed that are
affected by multiple vulnerabilities:

  - 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)

  - GStreamer EXIF Metadata Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability
    allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with
    this library is required to exploit this vulnerability but attack vectors may vary depending on the
    implementation. The specific flaw exists within the parsing of EXIF metadata. The issue results from the
    lack of proper validation of user-supplied data, which can result in an integer overflow before allocating
    a buffer. An attacker can leverage this vulnerability to execute code in the context of the current
    process. . Was ZDI-CAN-23896. (CVE-2024-4453)

  - 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-2024-47538)

  - GStreamer is a library for constructing graphs of media-handling components. An OOB-write vulnerability
    has been identified in the gst_ssa_parse_remove_override_codes function of the gstssaparse.c file. This
    function is responsible for parsing and removing SSA (SubStation Alpha) style override codes, which are
    enclosed in curly brackets ({}). The issue arises when a closing curly bracket } appears before an
    opening curly bracket { in the input string. In this case, memmove() incorrectly duplicates a substring.
    With each successive loop iteration, the size passed to memmove() becomes progressively larger
    (strlen(end+1)), leading to a write beyond the allocated memory bounds. This vulnerability is fixed in
    1.24.10. (CVE-2024-47541)

  - GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference
    has been discovered in the id3v2_read_synch_uint function, located in id3v2.c. If id3v2_read_synch_uint is
    called with a null work->hdr.frame_data, the pointer guint8 *data is accessed without validation,
    resulting in a null pointer dereference. This vulnerability can result in a Denial of Service (DoS) by
    triggering a segmentation fault (SEGV). This vulnerability is fixed in 1.24.10. (CVE-2024-47542)

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