Synopsis: Low: krb5 security, bug fix, and enhancement update
Advisory ID: SLSA-2016:2591-2
Issue Date: 2016-11-03
CVE Numbers: CVE-2016-3119
 CVE-2016-3120
--

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)
