"A vulnerability has been discovered and corrected in krb5 :

The MIT krb5 KDC (Key Distribution Center) daemon can free an
uninitialized pointer while processing an unusual AS-REQ, corrupting
the process heap and possibly causing the daemon to abnormally
terminate. An attacker could use this vulnerability to execute
malicious code, but exploiting frees of uninitialized pointers to
execute code is believed to be difficult. It is possible that a
legitimate client that is misconfigured in an unusual way could
trigger this vulnerability (CVE-2012-1015).

The updated packages have been patched to correct this issue."
