data. A remote attacker could possibly use this issue to cause OpenLDAP to
crash, resulting in a denial of service. (CVE-2015-6908)

Update instructions

The problem can be corrected by updating your system to the following package versions:

In general, a standard system update will make all the necessary changes.
