REDHAT-BUG-2331740: High severity moonlight vulnerability
GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been detected in the function gstparsevorbissetuppacket within vorbisparse.c. The integer size is read from the input file without proper validation. As a result, size can exceed the fixed size of the pad->vorbismodesizes array (which size is 256). When this happens, the for loop overwrites the entire pad structure with 0s and 1s, affecting adjacent memory as well. This OOB-write can overwrite up to 380 bytes of memory beyond the boundaries of the pad->vorbismodesizes array. This vulnerability is fixed in 1.24.10.
