| Description: | Description:
The remote host is missing an update to openldap
announced via advisory MDVSA-2011:056.
Multiple vulnerabilities has been identified and fixed in openldap:
chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24,
when a master-slave configuration with a chain overlay and
ppolicy_forward_updates (aka authentication-failure forwarding) is
used, allows remote authenticated users to bypass external-program
authentication by sending an invalid password to a slave server
(CVE-2011-1024).
bind.cpp in back-ndb in OpenLDAP 2.4.x before 2.4.24 does not require
authentication for the root Distinguished Name (DN), which allows
remote attackers to bypass intended access restrictions via an
arbitrary password (CVE-2011-1025).
modrdn.c in slapd in OpenLDAP 2.4.x before 2.4.24 allows remote
attackers to cause a denial of service (daemon crash) via a relative
Distinguished Name (DN) modification request (aka MODRDN operation)
that contains an empty value for the OldDN field (CVE-2011-1081).
The updated packages have been patched to correct these issues.
Affected: 2010.0, 2010.1
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
