of Kerberos. The Common Vulnerabilities and Exposures project identifies
the following problems:

CVE-2014-4341 
An unauthenticated remote attacker with the ability to inject
packets into a legitimately established GSSAPI application session
can cause a program crash due to invalid memory references when
attempting to read beyond the end of a buffer.

CVE-2014-4342 
An unauthenticated remote attacker with the ability to inject
packets into a legitimately established GSSAPI application session
can cause a program crash due to invalid memory references when
reading beyond the end of a buffer or by causing a null pointer
dereference.

CVE-2014-4343 
An unauthenticated remote attacker with the ability to spoof packets
appearing to be from a GSSAPI acceptor can cause a double-free
condition in GSSAPI initiators (clients) which are using the SPNEGO
mechanism, by returning a different underlying mechanism than was
proposed by the initiator. A remote attacker could exploit this flaw
to cause an application crash or potentially execute arbitrary code.

CVE-2014-4344 
An unauthenticated or partially authenticated remote attacker can
cause a NULL dereference and application crash during a SPNEGO
negotiation by sending an empty token as the second or later context
token from initiator to acceptor.

CVE-2014-4345 
When kadmind is configured to use LDAP for the KDC database, an
authenticated remote attacker can cause it to perform an
out-of-bounds write (buffer overflow).";
