C* music player: Insecure temporary file usage — GLSA 200909-08

An insecure temporary file usage has been reported in the C* music player, allowing for symlink attacks.

Package	media-sound/cmus on all architectures
Affected versions	< 2.2.0-r1
Unaffected versions	>= 2.2.0-r1

The C* Music Player (cmus) is a modular and very configurable ncurses-based audio player.

Dmitry E. Oboukhov reported that cmus-status-display does not handle the "/tmp/cmus-status" temporary file securely.

A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.

There is no known workaround at this time.

All C* music player users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-sound/cmus-2.2.0-r1"
