Details

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)
