CVE-2009-4212 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4212):
  Multiple integer underflows in the (1) AES and (2) RC4 decryption
  functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3
  through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause
  a denial of service (daemon crash) or possibly execute arbitrary code
  by providing ciphertext with a length that is too short to be valid.

CVE-2010-0283 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0283):
  The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7
  before 1.7.2, and 1.8 alpha, allows remote attackers to cause a
  denial of service (assertion failure and daemon crash) via an invalid
  (1) AS-REQ or (2) TGS-REQ request.

The oldest version in the tree is now 1.8.3. A B3-rated vulnerability gets a GLSA vote.
