Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated Kerberos 5 packages available
Advisory ID: RHSA-2001:060-04
Issue date: 2001-04-26
Updated on: 2001-05-16
Product: Red Hat Linux
Keywords: kerberos ftpd glob
Cross references:
Obsoletes: RHSA-2001:025
---------------------------------------------------------------------
1. Topic:
Updated Kerberos 5 packages are now available for Red Hat Linux 6.2, 7,
and 7.1. These updates close a potential vulnerability present in the
gssapi-aware ftpd included in the krb5-workstation package.
2. Relevant releases/architectures:
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - i386
3. Problem description:
By use of a carefully-crafted authentication request, a malicious client
could exploit a vulnerability made possible by a missing bounds check. A
malicious client could also overflow the buffer space used by the server
for performing globbing operations.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
34372 - krb5-server-1.2.2-4.alpha.rpm i386 compatibility
35978 - gssftp can be segfaulted remotely, possibly exploitable

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>
