Kerberos KDC RC4 and AES Decryption Integer Underflow Vulnerabilities
http://web.mit.edu/kerberos/www/advisories/MITKRB5-SA-2009-004.txt

Integer underflow bugs in the AES and RC4 decryption operations of the crypto library of the MIT Kerberos software can cause crashes, heap corruption, or, under extraordinarily unlikely conditions, arbitrary code execution. Only releases krb5-1.3 and later are vulnerable, as earlier releases did not contain the functionality implemented by the vulnerable code.
