RHSA-2004:448-01: Updated krb5 packages
Posted by Philipp Esselbach on: 08/31/2004 04:14 PM [ Print | 0 comment(s) ]
Updated krb5 packages are available for Red Hat Enterprise Linux 2.1
----------------------------------------------------------------------
Red Hat Security Advisory
Synopsis: Updated krb5 packages fix security vulnerabilities
Advisory ID: RHSA-2004:448-01
Issue date: 2004-08-31
Updated on: 2004-08-31
Product: Red Hat Enterprise Linux
Keywords: krb5 double-free asn.1
Obsoletes: RHSA-2004:236
CVE Names: CAN-2004-0642 CAN-2004-0643 CAN-2004-0644
----------------------------------------------------------------------
1. Summary:
Updated Kerberos (krb5) packages that correct double-free and ASN.1 parsing bugs are now available for Red Hat Enterprise Linux.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
Kerberos is a networked authentication system that uses a trusted third party (a KDC) to authenticate clients and servers to each other.
Several double-free bugs were found in the Kerberos 5 KDC and libraries. A remote attacker could potentially exploit these flaws to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0642 and CAN-2004-0643 to these issues.
A double-free bug was also found in the krb524 server (CAN-2004-0772), however this issue was fixed for Red Hat Enterprise Linux 2.1 users by a previous erratum, RHSA-2003:052.
An infinite loop bug was found in the Kerberos 5 ASN.1 decoder library. A remote attacker may be able to trigger this flaw and cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0644 to this issue.
All users of krb5 should upgrade to these updated packages, which contain backported security patches to resolve these issues.
