    Description :
    Kerberos V5 is a trusted-third-party network authentication system,
    which can improve your network's security by eliminating the insecure
    practice of sending passwords over the network in unencrypted form.
    Security issues fixed with this release:
    CVE-2013-1418
    The setup_server_realm function in main.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka
    krb5) before 1.10.7, when multiple realms are configured, allows remote attackers to cause a denial of
    service (NULL pointer dereference and daemon crash) via a crafted request.
    CVE-2013-6800
    An unspecified third-party database module for the Key Distribution Center (KDC) in MIT Kerberos 5 (aka
    krb5) 1.10.x allows remote authenticated users to cause a denial of service (NULL pointer dereference and
    daemon crash) via a crafted request, a different vulnerability than CVE-2013-1418.
    CVE-2014-4341
    MIT Kerberos 5 (aka krb5) before 1.12.2 allows remote attackers to cause a denial of service (buffer over-
    read and application crash) by injecting invalid tokens into a GSSAPI application session.
    CVE-2014-4342
    MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of
    service (buffer over-read or NULL pointer dereference, and application crash) by injecting invalid tokens
    into a GSSAPI application session.
    CVE-2014-4343
    Double free vulnerability in the init_ctx_reselect function in the SPNEGO initiator in
    lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.10.x through 1.12.x before 1.12.2 allows
    remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via
    network traffic that appears to come from an intended acceptor, but specifies a security mechanism
    different from the one proposed by the initiator.
    CVE-2014-4344
    The acc_ctx_cont function in the SPNEGO acceptor in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka
    krb5) 1.5.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (NULL
    pointer dereference and application crash) via an empty continuation token at a certain point during a
    SPNEGO negotiation.
    CVE-2014-4345
    Off-by-one error in the krb5_encode_krbsecretkey function in
    plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the LDAP KDB module in kadmind in MIT Kerberos 5 (aka
    krb5) 1.6.x through 1.11.x before 1.11.6 and 1.12.x before 1.12.2 allows remote authenticated users to
    cause a denial of service (buffer overflow) or possibly execute arbitrary code via a series of cpw
    -keepold commands.
    Fixed bugs;
    These updated krb5 packages also include several bug fixes.
    Please see changelog for more information.
