CVE-2011-2161

Publication date 20 May 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The ape_read_header function in ape.c in libavformat in FFmpeg before 0.5.4, as used in MPlayer, VideoLAN VLC media player, and other products, allows remote attackers to cause a denial of service (application crash) via an APE (aka Monkey's Audio) file that contains a header but no frames.
