The version of gstreamer1-plugins-base installed on the remote host is prior to 1.18.4-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2971 advisory.

    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)

    GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has     been detected in the format_channel_mask function in gst-discoverer.c. The vulnerability affects the local     array position, which is defined with a fixed size of 64 elements. However, the function     gst_discoverer_audio_info_get_channels may return a guint channels value greater than 64. This causes the     for loop to attempt access beyond the bounds of the position array, resulting in an OOB-read when an index     greater than 63 is used. This vulnerability can result in reading unintended bytes from the stack.
    Additionally, the dereference of value->value_nick after the OOB-read can lead to further memory     corruption or undefined behavior. This vulnerability is fixed in 1.24.10. (CVE-2024-47600)

    GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference     vulnerability has been detected in the parse_lrc function within gstsubparse.c. The parse_lrc function     calls strchr() to find the character ']' in the string line. The pointer returned by this call is then     passed to g_strdup(). However, if the string line does not contain the character ']', strchr() returns     NULL, and a call to g_strdup(start + 1) leads to a null pointer dereference. This vulnerability is fixed     in 1.24.10. (CVE-2024-47835)

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