Fedora Core 1 : krb5-1.3.4-5 (2004-276)

Synopsis :

The remote Fedora Core host is missing a security update.

Description :

Kerberos is a networked authentication system which 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 CVE-2004-0642 and
CVE-2004-0643 to these issues.

A double-free bug was also found in the krb524 server (CVE-2004-0772),
however this issue does not affect Fedora Core.

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 CVE-2004-0644 to this issue.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
