Descriptions

ns-slapd in 389 Directory Server before 1.3.0.8 allows remote attackers to cause a denial of service (server crash) via a crafted Distinguished Name (DN) in a MOD operation request.

ns-slapd en 389 Directory Server anterior a v1.3.0.8 permite a atacantes remotos provocar una denegación de servicio (caída del servidor) a través de un Distinguished Name (DN) manipulado en una operación de petición MOD.

The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol server and command-line utilities for server administration. It was discovered that the 389 Directory Server did not properly handle the receipt of certain MOD operations with a bogus Distinguished Name. A remote, unauthenticated attacker could use this flaw to cause the 389 Directory Server to crash. All 389-ds-base users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the 389 server service will be restarted automatically.
