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

5. RPMs required:

Red Hat Linux 9:

SRPMS:
ftp://updates.redhat.com/9/en/os/SRPMS/openoffice-1.0.2-11.src.rpm

i386:
ftp://updates.redhat.com/9/en/os/i386/openoffice-1.0.2-11.i386.rpm

ftp://updates.redhat.com/9/en/os/i386/openoffice-libs-1.0.2-11.i386.rpm

6. Verification:

MD5 sum Package Name

These packages are GPG signed by Red Hat for security. Our key is available from https://www.redhat.com/security/team/key.html

You can verify each package with the following command:

rpm --checksig -v

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command:

md5sum

Red Hat Security Advisory

Synopsis: Updated libpng packages fix crash
Advisory ID: RHSA-2004:181-01

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.

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.

Red Hat Security Advisory

Synopsis: Updated utempter package fixes vulnerability
Advisory ID: RHSA-2004:175-01
Issue date: 2004-04-30
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.

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.
