Detail

Synopsis

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

Background

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

Description

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

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All C* music player users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =media-sound/cmus-2.2.0-r1
