Updated on: 2004-04-30
Product: Red Hat Linux
Keywords:
Cross references:
Obsoletes:
CVE Names: CAN-2004-0409
1. Topic:
An updated X-Chat package fixes a vulnerability which could be
exploited by a malicious Socks-5 proxy is now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
X-Chat is a graphical IRC chat client for the X Window
System.
A stack buffer overflow flaw was found in the X-Chat’s Socks-5
proxy code. An attacker could create a malicious Socks-5 proxy
server in such a way that X-Chat would execute arbitrary code if a
victim configured X-Chat to use the proxy.
Users of X-Chat should upgrade to this updated package which
contains a backported security patch and is 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.
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

Red Hat Security Advisory
Synopsis: An updated LHA package fixes security
vulnerabilities
Advisory ID: RHSA-2004:179-01
Issue date: 2004-04-30
Updated on: 2004-04-30
Product: Red Hat Linux
Keywords:
Cross references:
Obsoletes:
CVE Names: CAN-2004-0234 CAN-2004-0235
1. Topic:
An updated LHA package that fixes several security
vulnerabilities is now available.
2. Relevant releases/architectures:
Red Hat Linux 9 – i386
3. Problem description:
LHA is an archiving and compression utility for LHarc format
archives.
Ulf Harnhammar discovered two stack buffer overflows and two
directory traversal flaws in LHA. An attacker could exploit the
buffer overflows by creating a carefully crafted LHA archive in
such a way that arbitrary code would be executed when the archive
is tested or extracted by a victim. The Common Vulnerabilities and
Exposures project (cve.mitre.org/) has assigned the name
CAN-2004-0234 to this issue. An attacker could exploit the
directory traversal issues to create files as the victim outside of
the expected directory. The Common Vulnerabilities and Exposures
project (cve.mitre.org/) has
assigned the name CAN-2004-0235 to this issue.
Users of LHA should update to this updated packages which
contain backported patches not vulnerable to these issues.
Red Hat would like to thank Ulf Harnhammar for disclosing and
providing test cases and patches for these issues.
