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

High Nessus Plugin ID 14592


The remote Fedora Core host is missing a security update.


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.


Update the affected packages.
