The deref overlay in slapd 2.4.13 through 2.4.40 dereferences a NULL pointer when a search request includes the Deref control with an empty list of attributes to return (missing input validation). Fix: http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=c32e74763f77675b9e144126e375977ed6dc562c References: http://www.openldap.org/its/?findid=8027 http://bugs.debian.org/776988 Certain search queries including the Matched Values control can trigger a double free in slapd 2.4.40 when freeing operation controls. This is a regression in 2.4.40, no earlier releases are affected. Fix: http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=2f1a2dd329b91afe561cd06b872d09630d4edb6a References: http://www.openldap.org/its/?findid=8046 http://bugs.debian.org/776991 May we have CVEs assigned to these, please? thanks, Ryan Download attachment "signature.asc" of type "application/pgp-signature" (837 bytes)
