CVE-2021-30014Public exploit

Denial of service via unchecked negative PPS ID

Published Apr 19, 2021 · Updated Mar 5, 2025

Integer overflow in GPAC 0.9.0-preview through 1.0.1 allows local users to crash the process by parsing a crafted HEVC file. hevc_parse_slice_segment accepts a negative pps_id from gf_bs_read_ue_log because it checks only whether the value is at least 64, then uses it to index the HEVC PPS array. Processing attacker-controlled HEVC content is required, and the documented consequence is a process crash rather than data disclosure or modification.
