"A buffer overflow vulnerability exists in nss_ldap versions prior to
198. When nss_ldap is configured without a value for the 'host'
keyword, it attempts to configure itself using SRV records stored in
DNS. nss_ldap does not check that the data returned by the DNS query
will fit into an internal buffer, thus exposing it to an overflow.

A similar issue exists in versions of nss_ldap prior to 199 where
nss_ldap does not check that the data returned by the DNS query has
not been truncated by the resolver libraries to avoid a buffer
overflow. This can make nss_ldap attempt to parse more data than what
is actually available, making it vulnerable to a read buffer overflow.

Finally, a format string bug in the logging function of pam_ldap prior
to version 144 exist.

All users are recommended to upgrade to these updated packages. Note
that the nss_ldap packages for 7.2, 8.0, and Single Network Firewall
7.2 contain the pam_ldap modules."
