CVE-2014-125025Network attack vector

Decoder crash via unchecked AAC pulse positions

Published Jun 19, 2022 · Updated Apr 15, 2025

Out-of-bounds read in FFmpeg 2.0 allows attackers to crash media-processing applications via a crafted AAC stream. The decode_pulses function checks decoded pulse positions against 1023 instead of the active scalefactor-band limit, permitting an array read beyond valid coefficients. A media-processing application must decode attacker-controlled AAC data; the resulting invalid read can terminate that process.
