Red Hat, Inc. Security Advisory
Synopsis: Updated Kerberos 5 packages are now available for Red Hat Linux.
Advisory ID: RHSA-2000:025-05
Issue date: 2000-05-16
Updated on: 2000-05-17
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.
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

These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:
http://www.redhat.com/corp/contact.html
You can verify each package with the following command:
rpm --checksig <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>
