"openldap2 was updated to fix two security issues and one non-security
bug.

The following vulnerabilities were fixed :

  - A remote attacker could cause a denial of service
    through a NULL pointer dereference and crash via an
    empty attribute list in a deref control in a search
    request. (bnc#916897 CVE-2015-1545)

  - A remote attacker could cause a denial of service
    (crash) via a crafted search query with a matched values
    control. (bnc#916914 CVE-2015-1546)

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
