RHSA-2007:0701 - Security Advisory

Topic

An updated xterm package that corrects a security issue is now available
for Red Hat Enterprise Linux 4.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

Description

The xterm program is a terminal emulator for the X Window System. It
provides DEC VT102 and Tektronix 4014 compatible terminals for
programs that cannot use the window system directly.

A bug was found in the way xterm packages were built that caused the
pseudo-terminal device files of the xterm emulated terminals to be owned by
the incorrect group. This flaw did not affect Red Hat Enterprise Linux 4
Update 4 and earlier. (CVE-2007-2797)

All users of xterm are advised to upgrade to this updated package, which
contains a patch to correct this issue.
