Summary: Updated kernel packages that fix a number of security issues as well as other bugs are now available for Red Hat Enterprise Linux 2.1 (64 bit architectures) This security advisory has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 3. Problem description: The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the security issues described below: * a flaw in the ATM subsystem affecting systems with installed ATM hardware and configured ATM support that allowed a remote user to cause a denial of service (panic) by accessing socket buffer memory after it has been freed (CVE-2006-4997, Moderate) * a flaw in the DVD handling of the CDROM driver that could be used together with a custom built USB device to gain root privileges (CVE-2006-2935, Moderate) In addition to the security issues described above, the following bugs are also addressed: * a potential overflow condition when reading /proc/devices * a potential page corruption bug in /proc/kcore All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to these updated packages, which contain backported fixes to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. 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.
