Check for the version of the krb packages Detailed Explanation for this Vulnerability Assessment Updated Kerberos (krb5) packages that correct buffer overflow and temporary file 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. A heap based buffer overflow bug was found in the administration library of Kerberos 1.3.5 and earlier. This bug could permit an authenticated remote attacker to execute arbitrary commands on a realm's master Kerberos KDC. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1189 to this issue. Additionally a temporary file bug was found in the Kerberos krb5-send-pr program. It is possible that a possible hacker could create a temporary file that would permit an arbitrary file to be overwritten which the victim has write access to. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0971 to this issue. All users of krb5 should upgrade to these updated packages, which contain backported security patches to resolve these issues.
