Subject: [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

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
