Title:C* music player: Insecure temporary file usage
Date:09/09/2009
Bugs: #250474
ID:200909-08

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.

Affected packages

Package Vulnerable Unaffected Architecture(s)
media-sound/cmus < 2.2.0-r1 >= 2.2.0-r1 All supported architectures

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"
