Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC.
A flaw was found in the way the Kerberos Authentication Service and Key Distribution Center server (krb5kdc) handled Kerberos v4 protocol packets. An unauthenticated remote attacker could use this flaw to crash the krb5kdc daemon, disclose portions of its memory, or possibly execute arbitrary code using malformed or truncated Kerberos v4 protocol requests. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2008-0062 and CVE-2008-0063 to this issue.
A flaw was found in the RPC library used by the Kerberos kadmind server. An unauthenticated remote attacker could use this flaw to crash kadmind. This issue only affected systems with certain resource limits configured and did not affect systems using default resource limits used by Red Hat Enterprise Linux 2.1 or 3. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-0948 to this issue.
