CVE-2022-38855

Application crash via unchecked MOV sample data

Published Sep 15, 2022 · Updated Aug 3, 2024

Out-of-bounds write in MPlayer and MEncoder SVN-r38374-13.0.1 allows attackers to crash the application via a crafted MOV file. The gen_sh_video path in libmpdemux/demux_mov.c accesses undersized MOV sample-description data without the bounds checks added in upstream revision r38384. A user must open the file, and the published NVD impact is limited to an application crash with no confidentiality or integrity effect.
