Problem Description:
A vulnerability has been discovered in xterm, which can be exploited
by malicious people to compromise a user's system. The vulnerability
is caused due to xterm not properly processing the DECRQSS Device
Control Request Status String escape sequence. This can be exploited
to inject and execute arbitrary shell commands by e.g. tricking a
user into displaying a malicious text file containing a specially
crafted escape sequence via the more command in xterm (CVE-2008-2383).
The updated packages have been patched to prevent this.
(And try dealing with Microsoft licensing sometime if you think security
communication is lacking)

Two stack-based buffer overflows in the read_special_escape() function
in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research
discovered a vulnerability related to the "setfilename" command
(CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability
related to the "font" escape sequence (CVE-2008-4306).
