CVE-2022-38862

Memory corruption via out-of-bounds write in play

Published Sep 15, 2022 · Updated Aug 3, 2024

Out-of-bounds write in MPlayer and MEncoder SVN-r38374-13.0.1 allows attackers to corrupt memory during media processing. The play() function at libaf/af.c line 639 writes past the intended buffer while the audio-filter path processes data. Triggering requires local execution and user interaction; public records do not establish whether the result is limited to a crash or enables code execution.
