A vulnerability in rxvt-unicode may allow a remote attacker to execute arbitrary code.
|Package||x11-terms/rxvt-unicode on all architectures|
|Affected versions||< 9.22-r9|
|Unaffected versions||>= 9.22-r9|
rxvt-unicode (urxvt) is a clone of the rxvt terminal emulator.
It was discovered that rxvt-unicode did not properly handle certain escape sequences.
A remote attacker could entice a user to run a program where attacker controls the output inside a rxvt terminal window, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All rxvt-unicode users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-terms/rxvt-unicode-9.22-r9"
