CVE-2024-47541: GHSL-2024-228: OOB-write in subparse/gstssaparse.c in GStreamer - CVE-2024-47541
GStreamer is a library for constructing graphs of media-handling components. An OOB-write vulnerability has been identified in the gstssaparseremoveoverridecodes 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.
