Amazon Linux AMI Security Advisory: ALAS-2013-184
Advisory Release Date: 2014-09-15 22:52 Pacific
It was found that the 389 Directory Server did not properly restrict access to entries when the "nsslapd-allow-anonymous-access" configuration setting was set to "rootdse". An anonymous user could connect to the LDAP database and, if the search scope is set to BASE, obtain access to information outside of the rootDSE. (CVE-2013-1897 )
Run yum update 389-ds-base to update your system.
