A buffer overflow in tmux might allow remote attacker(s) to execute arbitrary code.
|Package||app-misc/tmux on all architectures|
|Affected versions||< 3.1c|
|Unaffected versions||>= 3.1c|
tmux is a terminal multiplexer.
A flaw in tmux’s handling of escape characters was discovered which may allow a buffer overflow.
A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
There is no known workaround at this time.
All tmux users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-misc/tmux-3.1c"
