[RHSA-2000:025-07] Updated Kerberos 5 packages are now available for Red Hat Linux.
--------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: Updated Kerberos 5 packages are now available for Red Hat Linux. Advisory ID: RHSA-2000:025-07 Issue date: 2000-05-16 Updated on: 2000-05-18 Product: Red Hat Linux Keywords: N/A Cross references: N/A --------------------------------------------------------------------- 1. Topic: Security vulnerabilities have been found in the Kerberos 5 implementation shipped with Red Hat Linux 6.2. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386 alpha sparc 3. Problem description: A number of possible buffer overruns were found in libraries included in the affected packages. A denial-of-service vulnerability was also found in the ksu program. * A remote user may gain unauthorized root access to a machine running services authenticated with Kerberos 4. * A remote user may gain unauthorized root access to a machine running krshd, regardless of whether the program is configured to accept Kerberos 4 authentication. * A local user may gain unauthorized root access by exploiting v4rcp or ksu. A packaging error was discovered in the original set of updates. This set of update packages includes no functional differences compared to the previously-released set. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 10653 - ''stat'' unresolved on "libkrb5.so.2.2" load 11496 - security-updated krb5 packages fail dependencies 6.
