Detail
| Problem Description: Updated krb5 packages are now available for Red Hat Enterprise Linux 4 to correct a privilege escalation security flaw. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. A flaw was found where some bundled Kerberos-aware applications would fail to check the result of the setuid() call. On Linux 2.6 kernels, the setuid() call can fail if certain user limits are hit. A local attacker could manipulate their environment in such a way to get the applications to continue to run as root, potentially leading to an escalation of privileges. (CVE-2006-3083). Users are advised to update to these erratum packages which contain a backported fix to correct this issue. 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. Bug IDs fixed (http://bugzilla.redhat.com/): 197818 - CVE-2006-3083 krb5 multiple unsafe setuid usage |
