Check for the version of the krb packages Detailed Explanation for this Vulnerability Assessment Updated Kerberos (krb5) packages that correct double-free and ASN.1 parsing bugs are now available for Red Hat Enterprise Linux. 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 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 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 CVE-2004-0644 to this issue. All users of krb5 should upgrade to these updated packages, which contain backported security patches to resolve these issues.
