"Jonathan Clarke discovered that the OpenLDAP slapd server did not
properly handle modify requests when using the Berkeley DB backend and
specifying the NOOP control. An authenticated user with modify
permissions could send a crafted modify request and cause a denial of
service via application crash. Ubuntu 7.10 is not affected by this
issue. (CVE-2007-6698)

Ralf Haferkamp discovered that the OpenLDAP slapd server did not
properly handle modrdn requests when using the Berkeley DB backend and
specifying the NOOP control. An authenticated user with modrdn
permissions could send a crafted modrdn request and possibly cause a
denial of service via application crash. (CVE-2007-6698).

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."
