## Description

FFmpeg 2.x allows remote attackers to conduct cross-origin attacks and read
arbitrary files by using the subfile protocol in an HTTP Live Streaming
(HLS) M3U8 file, leading to an external HTTP request in which the URL
string contains an arbitrary line of a local file.

### From the Ubuntu Security Team

It was discovered that Libav incorrectly handled certain media
files. An attacker could possibly use this issue to cause a denial of
service or other unspecified impact.
