Red Hat Security Advisory
Synopsis: Updated CVS packages fix security issue 1. Topic: Updated cvs packages that fix a client vulnerability that could be exploited by a malicious server are now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: CVS is a version control system frequently used to manage source code repositories. Sebastian Krahmer discovered a flaw in CVS clients where rcs diff files can create files with absolute pathnames. An attacker could create a fake malicious CVS server that would cause arbitrary files to be created or overwritten when a victim connects to it. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0180 to this issue. Users of CVS are advised to upgrade to these erratum 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. 5. RPMs required: Red Hat Linux 9:
SRPMS:
i386: 6. Verification: MD5 sum Package Name
44ad2349b6b00275273280eac1a52e20 9/en/os/SRPMS/cvs-1.11.2-17.src.rpm 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 cadaver package fixes security vulnerability in neon
1. Topic:
An updated cadaver package that fixes a vulnerability in neon exploitable
by a malicious DAV server is now available.
2. Relevant releases/architectures:
Red Hat Linux 9 - i386
3. Problem description:
cadaver is a command-line WebDAV client that 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 cadaver. The
Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned
the name CAN-2004-0179 to this issue.
Users of cadaver are advised to upgrade to this updated package, which
contains 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:
