CVE-2013-4449

First published: Tue Oct 15 2013(Updated: )

It was discovered that OpenLDAP, with the rwm overlay to slapd, could segfault if a user were able to query the directory and immediately unbind from the server. This seems to be due to the rwm overlay not doing reference counting properly, so rwm_conn_destroy frees the session context while rwm_op_search is using it. This condition also seems to require multiple cores/CPUs to trigger. This was also reported upstream [1] and is currently unfixed.
