GHSL-2024-246: GStreamer has an OOB-read in qtdemux_merge_sample_table

GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been discovered in the qtdemux_merge_sample_table function within qtdemux.c. The problem is that the size of the stts buffer isn’t properly checked before reading stts_duration, allowing the program to read 4 bytes beyond the boundaries of stts->data. This vulnerability reads up to 4 bytes past the allocated bounds of the stts array. This vulnerability is fixed in 1.24.10.
