Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The following packages have been upgraded to a newer upstream version:
krb5 (1.14.1).

Security Fix(es) :

- A NULL pointer dereference flaw was found in MIT
Kerberos kadmind service. An authenticated attacker with
permission to modify a principal entry could use this
flaw to cause kadmind to dereference a NULL pointer and
crash by supplying an empty DB argument to the
modify_principal command, if kadmind was configured to
use the LDAP KDB module. (CVE-2016-3119)

- A NULL pointer dereference flaw was found in MIT
Kerberos krb5kdc service. An authenticated attacker
could use this flaw to cause krb5kdc to dereference a
NULL pointer and crash by making an S4U2Self request, if
the restrict_anonymous_to_tgt option was set to true.
(CVE-2016-3120)
