VULNERABILITY DETAILS

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Sun Microsystems Directory Service Manager. Authentication is not required to exploit this vulnerability.

The specific flaw exists within Sun Directory Server's LDAP implementation and can be triggered via a malformed LDAP query to the ns_slapd service. When the service decodes the malformed extendedRequest query containing a malformed requestValue string, the application will cause a buffer overflow which can lead to code execution under the context of the service.
