CVE-2024-47615: GHSL-2024-117: GStreamer has an out-of-bounds write in Ogg demuxer

First published: Wed Dec 11 2024(Updated: )

GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been detected in the function gst_parse_vorbis_setup_packet within vorbis_parse.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->vorbis_mode_sizes 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->vorbis_mode_sizes array. This vulnerability is fixed in 1.24.10.
