Vulnerability Description There exists a vulnerability in the Sun Directory Server. The flaw is caused due to improper handling of certain overly large LDAP messages. An unauthenticated remote attacker may exploit this vulnerability by sending a crafted LDAP message to the target host which may terminate the affected LDAP server on the target system.
The target server process will terminate as a result of an attack. Consequently, all established connections will be disconnected and further connections will not be possible until the server is manually restarted.
Vulnerability DetailsSun Directory Server is a distributed directory server based on the Lightweight Directory Access Protocol (LDAP). The server listens for LDAP requests on a port specified during installation. The default port assigned to the server during installation is randomly selected.
