Summary Service Console package krb5 has been updated to version krb5-1.2.7-70. 2. Relevant releases VMware ESX 3.5.0 without patch ESX350-200906407-SG 3. Problem Description a. Service Console package krb5 update to version krb5-1.2.7-70 Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. An input validation flaw in the asn1_decode_generaltime function in MIT Kerberos 5 before 1.6.4 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer. A remote attacker could use this flaw to crash a network service using the MIT Kerberos library, such as kadmind or krb5kdc, by causing it to dereference or free an uninitialized pointer or, possibly, execute arbitrary code with the privileges of the user running the service. NOTE: ESX by default is unaffected by this issue, the daemons kadmind and krb5kdc are not installed in ESX. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0846 to this issue.
