CVE-2022-2122

Application crash or heap overwrite via integer wraparound

Published Jul 19, 2022 · Updated Aug 3, 2024

Heap-based buffer overflow in GStreamer Good Plug-ins before 1.20.3 allows attackers to crash applications via crafted MP4 files. In qtdemux_inflate, repeated 4,096-byte growth of the unsigned output length can wrap before reallocation, leaving zlib to write beyond the heap buffer. A user or consuming application must process the malicious file; the result depends on the libc and platform and ranges from a segmentation-fault crash to heap corruption.
