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.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5831 advisory.

    Package        : gst-plugins-base1.0     CVE ID         : CVE-2024-47538 CVE-2024-47541 CVE-2024-47600                      CVE-2024-47607 CVE-2024-47615 CVE-2024-47835

    Multiple multiple vulnerabilities were discovered in plugins for the     GStreamer media framework and its codecs and demuxers, which may result     in denial of service or potentially the execution of arbitrary code if     a malformed media file is opened.

    For the stable distribution (bookworm), these problems have been fixed in     version 1.22.0-3+deb12u3.

    We recommend that you upgrade your gst-plugins-base1.0 packages.

    For the detailed security status of gst-plugins-base1.0 please refer to     its security tracker page at:
