Fedora Core 1 2004-276: krb5 |

Check for the version of the krb5 package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory FEDORA-2004-276 (krb5). Kerberos V5 is a trusted-third-party network authentication system, which can improve your network's security by eliminating the insecure practice of cleartext passwords. Update Information: 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.
