Oracle Solaris Third-Party Patch Update : kerberos (multiple_input_validation_vulnerabilities_in)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote Solaris system is missing a security patch for third-party
software.

Description :

The remote Solaris system is missing necessary patches to address
security updates :

- The krb5_ldap_lockout_audit function in the Key
Distribution Center (KDC) in MIT Kerberos 5 (aka krb5)
1.8 through 1.8.4 and 1.9 through 1.9.1, when the LDAP
back end is used, allows remote attackers to cause a
denial of service (assertion failure and daemon exit)
via unspecified vectors, related to the locked_check_p
function. NOTE: the Berkeley DB vector is covered by
CVE-2011-4151. (CVE-2011-1528)

- The lookup_lockout_policy function in the Key
Distribution Center (KDC) in MIT Kerberos 5 (aka krb5)
1.8 through 1.8.4 and 1.9 through 1.9.1, when the db2
(aka Berkeley DB) or LDAP back end is used, allows
remote attackers to cause a denial of service (NULL
pointer dereference and daemon crash) via vectors that
trigger certain process_as_req errors. (CVE-2011-1529)

- The krb5_db2_lockout_audit function in the Key
Distribution Center (KDC) in MIT Kerberos 5 (aka krb5)
1.8 through 1.8.4, when the db2 (aka Berkeley DB) back
end is used, allows remote attackers to cause a denial
of service (assertion failure and daemon exit) via
unspecified vectors, a different vulnerability than
CVE-2011-1528. (CVE-2011-4151)
