===================================================================== CERT-Renater Note d'Information No. 2001/VULN296 _____________________________________________________________________ DATE : 19/10/2001 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Linux Red Hat Linux 7.1 ====================================================================== --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: New kernel 2.4 packages are available Advisory ID: RHSA-2001:129-05 Issue date: 2001-10-09 Updated on: 2001-10-18 Product: Red Hat Linux Keywords: ptrace local root kernel Cross references: Obsoletes: --------------------------------------------------------------------- 1. Topic: A vulnerability has been found in the ptrace code of the kernel (ptrace is the part that allows program debuggers to run) that could be abused by local users to gain root privileges. 2. Relevant releases/architectures: Red Hat Linux 7.1 - alpha, i386, i586, i686, ia64, noarch 3. Problem description: 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. The procedure for upgrading the kernel is documented at: http://www.redhat.com/support/docs/howto/kernel-upgrade/kernel-upgrade.html Please read the directions for your architecture carefully before proceeding with the kernel upgrade. Please note that this update is also available via Red Hat Network. Many people find this to be 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. Note that you need to select the kernel explicitly on default configurations of up2date. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 6.
