The vulnerability is caused by improper handling of certain malformed SubRip subtitle files. When the parser encounters specially crafted data, it can trigger a NULL pointer dereference, leading to a crash of the application using GStreamer for media playback or processing.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02304-1 advisory.

    - CVE-2025-47808: Fixed NULL-pointer dereference in TMPlayer subtitle parser (bsc#1244404).
    - CVE-2025-47807: Fixed NULL-pointer dereference in SubRip subtitle parser (bsc#1244403).
    - CVE-2025-47806: Fixed stack buffer overflow in SubRip subtitle parser (bsc#1244407).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The version of GStreamer installed on the remote host is prior to 1.26.2. It is, therefore, is affected by multiple vulnerabilities, as follows:

  - A NULL-pointer dereference in the SubRip subtitle parser that can cause crashes for certain input     files. (CVE-2025-47807)

  - A NULL-pointer dereference in the TMPlayer subtitle parser that can cause crashes for certain input     files. (CVE-2025-47808)

  - An Out-of-bounds read in the MOV/MP4 demuxer that can cause crashes or potentially information leaks     for certain input files. (CVE-2025-47219)

  - An Out-of-bounds read in the MOV/MP4 demuxer that can cause crashes or potentially information leaks     for certain input files. (CVE-2025-47183)

  - A stack buffer overflow in the SubRip subtitle parser that can cause crashes for certain input     files. (CVE-2025-47806)

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