Summary

nss_ldap 181 to versions before 213, as used in Mandrake Corporate Server and Mandrake 10.0, and other operating systems, does not properly handle a SIGPIPE signal when sending a search request to an LDAP directory server, which might allow remote attackers to cause a denial of service (crond and other application crash) if they can cause an LDAP server to become unavailable. NOTE: it is not clear whether this attack scenario is sufficient to include this item in CVE.

of the 'ssl start_tls' setting in ldap.conf.

As well, a bug in nss_ldap in Corporate Server and Mandrake 10.0 has
been fixed that caused crond, and other applications, to crash as a
result of clients receiving a SIGPIPE signal when attempting to issue
a new search request to a directory server that is no longer
available.

The updated packages have been patched to address this issue."
