CVE-2014-125014Network attack vector

Process crash via signed parameter-set identifiers

Published Jun 18, 2022 · Updated Apr 15, 2025

Out-of-bounds write in FFmpeg 2.0 HEVC decoding allows attackers to crash the process with a crafted HEVC bitstream. The signed vps_id and sps_id fields in libavcodec/hevc.h overflow into negative values that drive out-of-array accesses. Processing attacker-supplied HEVC media is required; published impact is limited to availability, with no reported data disclosure or modification.
