                   Red Hat Security Advisory

Synopsis:          Low: xterm security update
Advisory ID:       RHSA-2007:0701-02
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2007-0701.html
Issue date:        2007-11-15
Updated on:        2007-11-15
Product:           Red Hat Enterprise Linux
Keywords:          tty owner group
CVE Names:         CVE-2007-2797 
- - ---------------------------------------------------------------------

1. Summary:

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/):

239070 - CVE-2007-2797 Wrong settings for the tty (mesg: error: tty device is not owned by group `tty')
