Red Hat Security Advisory 2015-1840-01 - OpenLDAP is an open source suite of Lightweight Directory Access Protocol applications and development tools. LDAP is a set of protocols used to access and maintain distributed directory information services over an IP network. The openldap package contains configuration files, libraries, and documentation for OpenLDAP. A flaw was found in the way the OpenLDAP server daemon parsed certain Basic Encoding Rules data. A remote attacker could use this flaw to crash slapd via a specially crafted packet. All openldap users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
