Title:	RedHat Update for krb5 RHSA-2016:2591-02
Summary:	The remote host is missing an update for the 'krb5'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'krb5' package(s) announced via the referenced advisory. Vulnerability Insight: Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC). The following packages have been upgraded to a newer upstream version: krb5 (1.14.1). (BZ#1292153) 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) Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section. Affected Software/OS: krb5 on Red Hat Enterprise Linux Server (v. 7) Solution: Please Install the Updated Packages. CVSS Score: 4.0 CVSS Vector: AV:N/AC:L/Au:S/C:N/I:N/A:P
