Red Hat Security Advisory
Synopsis: Updated OpenOffice packages fix security vulnerability
in neon
Advisory ID: RHSA-2004:163-01
Issue date: 2004-04-30
Updated on: 2004-04-30
Product: Red Hat Linux
Keywords:
Cross references:
Obsoletes:
CVE Names: CAN-2004-0179
1. Topic:
Updated OpenOffice packages that fix a vulnerability in neon
exploitable by a malicious DAV server are now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
OpenOffice.org is an Open Source, community-developed,
multi-platform office productivity suite. OpenOffice internally
uses inbuilt code from neon, an HTTP and WebDAV client library.
Versions of the neon client library up to and including 0.24.4
have been found to contain a number of format string bugs. An
attacker could create a malicious WebDAV server in such a way as to
allow arbitrary code execution on the client should a user connect
to it using OpenOffice. The Common Vulnerabilities and Exposures
project (cve.mitre.org/) has
assigned the name CAN-2004-0179 to this issue.
Users of OpenOffice are advised to upgrade to these updated
packages, which contain a patch correcting this issue.
4. Solution:
Before applying this update, make sure all previously released
errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade.
Only those RPMs which are currently installed will be updated.
Those RPMs which are not installed but included in the list will
not be updated. Note that you can also use wildcards (*.rpm) if
your current directory only contains the desired RPMs.
Please note that this update is also available via Red Hat
Network. Many people find this an easier way to apply updates. To
use Red Hat Network, launch the Red Hat Update Agent with the
following command:
up2date
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the up2date
client with an updated certificate. The latest version of up2date
is available from the Red Hat FTP site and may also be downloaded
directly from the RHN website:
https://rhn.redhat.com/help/latest-up2date.pxt

Synopsis: Updated libpng packages fix crash

CVE Names: CAN-2004-0421
1. Topic:
Updated libpng packages that fix a out of bounds memory access
are now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
The libpng package contains a library of functions for creating
and manipulating PNG (Portable Network Graphics) image format
files.
Steve Grubb discovered a out of bounds memory access flaw in
libpng. An attacker could carefully craft a PNG file in such a way
that it would cause an application linked to libpng to crash when
opened by a victim. This issue may not be used to execute arbitrary
code.
Users are advised to upgrade to these updated packages that
contain a backported security fix not vulnerable to this issue.
4. Solution:
Before applying this update, make sure all previously released
errata relevant to your system have been applied.

Red Hat Security Advisory
Synopsis: Updated utempter package fixes vulnerability
Advisory ID: RHSA-2004:175-01

Updated on: 2004-04-30
Product: Red Hat Linux
Keywords:
Cross references:
Obsoletes:
CVE Names: CAN-2004-0233
1. Topic:
An updated utempter package that fixes a potential symlink
vulnerability is now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
Utempter is a utility that allows terminal applications such as
xterm and screen to update utmp and wtmp without requiring root
privileges.
Steve Grubb discovered a flaw in Utempter which allowed device
names containing directory traversal sequences such as ‘/../’. In
combination with an application that trusts the utmp or wtmp files,
this could allow a local attacker the ability to overwrite
privileged files using a symlink.
Users should upgrade to this new version of utempter, which
fixes this vulnerability.
4. Solution:
Before applying this update, make sure all previously released
errata relevant to your system have been applied.
