Topic: Updated cvs packages closing a vulnerability that could allow cvs to attempt to create files and directories in the root file system 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. A flaw was found in versions of CVS prior to 1.11.10 where a malformed module request could cause the CVS server to attempt to create files or directories at the root level of the file system. However, normal file system permissions would prevent the creation of these misplaced directories. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0977 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: ftp://updates.redhat.com/9/en/os/SRPMS/cvs-1.11.2-13.src.rpm i386: ftp://updates.redhat.com/9/en/os/i386/cvs-1.11.2-13.i386.rpm 6.

Our key is available from https://www.redhat.com/security/keys.html You can verify each package with the following command: rpm --checksig -v <filename> 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 <filename> 7.
