GHSL-2024-094: GStreamer has an OOB-write in isomp4/qtdemux.c

GStreamer is a library for constructing graphs of media-handling components. The program attempts to reallocate the memory pointed to by stream->samples to accommodate stream->n_samples + samples_count elements of type QtDemuxSample. The problem is that samples_count is read from the input file. And if this value is big enough, this can lead to an integer overflow during the addition. As a consequence, g_try_renew might allocate memory for a significantly smaller number of elements than intended. Following this, the program iterates through samples_count elements and attempts to write samples_count number of elements, potentially exceeding the actual allocated memory size and causing an OOB-write. This vulnerability is fixed in 1.24.10.

GStreamer 输入验证错误漏洞

GStreamer是GStreamer开源的一套用于处理流媒体的框架。 GStreamer存在输入验证错误漏洞，该漏洞源于当samples_count足够大时，则可能导致加法过程中出现整数溢出。
