A flaw was found in the GStreamer library. An integer overflow in the MP4/MOV demuxer's sample table parser can lead to out-of-bounds writes and NULL-pointer dereferences for certain input files. This vulnerability allows a malicious third party to trigger an application crash and, in the case of out-of-bounds writes, possibly allow code execution through heap manipulation.

Description A flaw was found in the GStreamer library. An out-of-bounds write in the MP4/MOV demuxer when handling CEA608 Closed Caption tracks can lead to crashes for certain input files. This vulnerability allows a malicious third party to trigger a crash of the application and perform code execution through heap manipulation.

A flaw was found in the Matroska/WebM demuxer in the GStreamer library. Processing a specially crafted input file can cause the usage of uninitialized stack memory, allowing calls to uninitialized function pointers, potentially resulting in code execution or an application crash.

A flaw was found in the MP4/MOV demuxer and memory allocator in the GStreamer library. Processing a specially crafted input file can cause an integer overflow in the qtdemux_parse_theora_extension function. This issue leads to a small amount of memory being allocated to store a large input size, resulting in an out-of-bounds write.

A flaw was found in the gdk-pixbuf decoder in the GStreamer library. Processing a specially crafted input file can cause a NULL pointer dereference due to an unchecked return value, resulting in an application crash and a denial of service.
