RHSA-2017:1852 - Moderate: openldap security, bug fix, and enhancement update

Synopsis

Moderate: openldap security, bug fix, and enhancement update

Type/Severity

Security Advisory Moderate

Topic

An update for openldap is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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:
