"Thomas Sesselmann discovered that the OpenLDAP slapd server did not
properly handle certain modify requests. A remote attacker could send
malicious modify requests to the server and cause a denial of service.
(CVE-2007-5707)

Toby Blake discovered that slapd did not properly terminate an array
while running as a proxy-caching server. A remote attacker may be able
to send crafted search requests to the server and cause a denial of
service. This issue only affects Ubuntu 7.04 and 7.10. (CVE-2007-5708).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
