Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC). The Public Key
Cryptography for Initial Authentication in Kerberos (PKINIT)
capability provides support for using public-key authentication with
A double-free flaw was found in the way the MIT Kerberos KDC handled
initial authentication requests (AS-REQ), when the KDC was configured
to provide the PKINIT capability. A remote attacker could use this
flaw to cause the KDC daemon to abort by using a specially crafted
AS-REQ request. (CVE-2011-0284)
