Security 10748 Published by

MandrakeSoft has released security updates for nss_ldap and perl-MailTools

nss_ldap

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.
