CVE-2024-47541Public exploit

Application crash via malformed SSA override codes

Published Dec 11, 2024 · Updated Nov 3, 2025

Out-of-bounds write in GStreamer gst-plugins-base before 1.24.10 allows local users to crash applications with a crafted SSA subtitle. In gst_ssa_parse_remove_override_codes, a closing brace before an opening brace makes memmove duplicate text while its copy length grows across loop iterations, eventually writing past the allocated buffer. Exploitation requires a GStreamer application to parse the malformed SSA content, and the documented consequence is process-memory corruption followed by an application crash.
