There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Double free vulnerability in the get_vrFilter function in servers/slapd/filter.c in OpenLDAP 2.4.40 allows
    remote attackers to cause a denial of service (crash) via a crafted search query with a matched values
    control. (CVE-2015-1546)

 - Admin Framework
 - Apache
 - ATS
 - Certificate Trust Policy
 - CFNetwork HTTPProtocol
 - CFNetwork Session
 - CFURL
 - CoreAnimation
 - FontParser
 - Graphics Driver
 - Hypervisor
 - ImageIO
 - IOHIDFamily
 - Kernel
 - LaunchServices
 - libnetcore
 - ntp
 - Open Directory Client
 - OpenLDAP
 - OpenSSL
 - PHP
 - QuickLook
 - SceneKit
 - ScreenSharing
 - Security - Code SIgning
 - UniformTypeIdentifiers
 - WebKit

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

OpenLDAP was updated to fix two security issues and one bug.
