tmux: Buffer overflow

Background

tmux is a terminal multiplexer.

Description

A flaw in tmux’s handling of escape characters was discovered which may allow a buffer overflow.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All tmux users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-misc/tmux-3.1c"
