Comment: -
Impact: Per: http://web.mit.edu/kerberos/advisories/MITKRB5-SA-2009-004.txt "Only releases krb5-1.3 and later are vulnerable, as earlier releases did not contain the functionality implemented by the vulnerable code. This is an implementation vulnerability in MIT krb5, and is not a vulnerability in the Kerberos protocol."
