Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
An error in the processing of special sequences in xterm may lead to
arbitrary commands execution.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
xterm is a terminal emulator for the X Window system.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Paul Szabo reported an insufficient input sanitization when processing
Device Control Request Status String (DECRQSS) sequences.
Impact
=3D=3D=3D=3D=3D=3D
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.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All xterm users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dx11-terms/xterm-239"
