CVE-2022-2453Public exploit

Application crash via freed quantization parameter

Published Jul 19, 2022 · Updated Aug 3, 2024

Use-after-free in GPAC before 2.1-DEV allows local users to crash MP4Box by processing a crafted BIFS scene file. During BIFS multi-field decoding, BD_DecMFFieldVec removes a quantization-parameter node on one path, while Q_IsTypeOn later reads the freed node. Triggering the flaw requires a user to process the supplied file with MP4Box; the demonstrated consequence is an invalid heap read and process termination.
