That also means that the bug is most probably located in the paged results code of either nss_ldap or libldap. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

is that somehow exploitable from a remote user? (e.g. via mail/web server) I don't think so. Additionally this bug is really only in libldap from OpenLDAP 2.4.X, which got the first real non-beta release a few weeks ago and we don't ship it in any products currently.
