Detail

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem 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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):
