  servers to authenticate to each other using symmetric encryption and a
  trusted third party, the Key Distribution Center (KDC).

  Multiple integer underflow flaws, leading to heap-based corruption, were
  found in the way the MIT Kerberos Key Distribution Center (KDC) decrypted
  ciphertexts encrypted with the Advanced Encryption Standard (AES) and
  ARCFOUR (RC4) encryption algorithms. If a remote KDC client were able to
  provide a specially-crafted AES- or RC4-encrypted ciphertext or texts, it
  could potentially lead to either a denial of service of the central KDC
  (KDC crash or abort upon processing the crafted ciphertext), or arbitrary
  code execution with the privileges of the KDC (i.e., root privileges).
  (CVE-2009-4212)

  All krb5 users should upgrade to these updated packages, which contain a
  backported patch to correct these issues. All running services using the
  MIT Kerberos libraries must be restarted for the update to take effect.");
