CVE-2023-0817Public exploit

Crash via unchecked MHAS sample-rate index

Published Feb 13, 2023 · Updated Mar 21, 2025

Buffer over-read in GPAC before 2.3.0-DEV allows context-dependent attackers to crash media processing via crafted MHAS input. The MHAS demuxer reads a five-bit sample-rate index but tests a zero-initialized rate variable before indexing the 28-entry USACSampleRates array. A user must cause GPAC to process the crafted media, and the demonstrated consequence is a process crash.
