mpv: Format string vulnerability

Background

Video player based on MPlayer/mplayer2.

Description

mpv uses untrusted input within format strings.

Impact

A remote attacker could entice a user to open a specially crafted m3u playlist file using mpv, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All mpv users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-video/mpv-0.33.1"
