An error in the processing of special sequences in xterm may lead to arbitrary commands execution.
|Package||x11-terms/xterm on all architectures|
|Affected versions||< 239|
|Unaffected versions||>= 239|
xterm is a terminal emulator for the X Window system.
Paul Szabo reported an insufficient input sanitization when processing Device Control Request Status String (DECRQSS) sequences.
A remote attacker could entice a user to display a file containing specially crafted DECRQSS sequences, possibly resulting in the remote execution of arbitrary commands with the privileges of the user viewing the file.
There is no known workaround at this time.
All xterm users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-terms/xterm-239"
