Detail

A race condition in nss_ldap, when used in applications that use pthread and fork after a call to nss_ldap, does not properly handle the LDAP connection, which might cause nss_ldap to return the wrong user data to the wrong process, giving one user access to data belonging to another user, in some cases.

The updated package hais been patched to prevent this issue.
