CVE-2013-4449
Michael Vishchers from Seven Principles AG discovered a denial of service vulnerability in slapd, the directory server implementation. When the server is configured to used the RWM overlay, an attacker can make it crash by unbinding just after connecting, because of an issue with reference counting.
CVE-2014-9713
The default Debian configuration of the directory database allows every users to edit their own attributes. When LDAP directories are used for access control, and this is done using user attributes, an authenticated user can leverage this to gain access to unauthorized resources.
Please note this is a Debian specific vulnerability.
The new package won't use the unsafe access control rule for new databases, but existing configurations won't be automatically modified. Administrators are incited to look at the README.Debian file provided by the updated package if they need to fix the access control rule.
CVE-2015-1545
Ryan Tandy discovered a denial of service vulnerability in slapd. When using the deref overlay, providing an empty attribute list in a query makes the daemon crashes.
