3. Description:
OpenLDAP is an open-source suite of Lightweight Directory Access Protocol
(LDAP) 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 packages contain configuration files, libraries,
and documentation for OpenLDAP.
The following packages have been upgraded to a later upstream version:
openldap (2.4.44). (BZ#1386365)
Security Fix(es):
* A double-free flaw was found in the way OpenLDAP's slapd server using the
MDB backend handled LDAP searches. A remote attacker with access to search
the directory could potentially use this flaw to crash slapd by issuing a
specially crafted LDAP search query. (CVE-2017-9287)
Additional Changes:
For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.4 Release Notes linked from the References section.
