CVE-2024-47606

GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in the function qtdemuxparsetheoraextension within qtdemux.c. The vulnerability occurs due to an underflow of the gint size variable, which causes size to hold a large unintended value when cast to an unsigned integer. This 32-bit negative value is then cast to a 64-bit unsigned integer (0xfffffffffffffffa) in a subsequent call to gstbuffernewandalloc. The function gstbuffernewallocate then attempts to allocate memory, eventually calling sysmemnewblock. The function sysmemnewblock adds alignment and header size to the (unsigned) size, causing the overflow of the 'slicesize' variable. As a result, only 0x89 bytes are allocated, despite the large input size. When the following memcpy call occurs in gstbufferfill, the data from the input file will overwrite the content of the GstMapInfo info structure. Finally, during the call to gstmemoryunmap, the overwritten memory may cause a function pointer hijack, as the mem->allocator->memunmapfull function is called with a corrupted pointer. This function pointer overwrite could allow an attacker to alter the execution flow of…
