Synopsis

An error in the processing of special sequences in xterm may lead to

arbitrary commands execution.

 

Background

xterm is a terminal emulator for the X Window system.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

Description

===========

 

Paul Szabo reported an insufficient input sanitization when processing

Device Control Request Status String (DECRQSS) sequences.

 

Impact

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

There is no known workaround at this time.

 

Resolution

==========

 

All xterm users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=x11-terms/xterm-239"
