Topic: Updated kernel packages that fix security vulnerabilities which may allow local users to gain root privileges are now available. These packages also resolve other minor issues. 2. Relevant releases/architectures: Red Hat Linux 9 - athlon, i386, i686 3. Problem description: The Linux kernel handles the basic functions of the operating system. Paul Starzetz discovered a flaw in return value checking in mremap() in the Linux kernel versions 2.4.24 and previous that may allow a local attacker to gain root privileges. No exploit is currently available; however this issue is exploitable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0077 to this issue. The Vicam USB driver in kernel versions prior to 2.4.25 does not use the copy_from_user function to access userspace, which crosses security boundaries. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0075 to this issue. Arjan van de Ven discovered a flaw in ncp_lookup() in ncpfs that could allow local privilege escalation. ncpfs is only used to allow a system to mount volumes of NetWare servers or print to NetWare printers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0010 to this issue. Alan Cox found issues in the R128 Direct Render Infrastructure that could allow local privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0003 to this issue. All users are advised to upgrade to these errata packages, which contain backported security patches that correct these issues.=20=20=20 Red Hat would like to thank Paul Starzetz from ISEC for reporting the issue CAN-2004-0077. 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.
