Active Directory services are the keystone of modern Windows networks, so this vulnerability, which allows a remote attacker to gain complete control of the server, along with the denial of service covered by the same patch are extremely serious. IBM ISS X-Force recommends that administrators immediately enable protection and plan patching activity with the highest priority. |

| Technical Description: |
Microsoft Windows is vulnerable to a buffer overflow, caused by improper bounds checking of LDAP requests by Active Directory. By sending a specially-crafted LDAP request containing a larger than expected number of convertible attributes, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the server to crash. |
| Remediation: |
Microsoft has released a patch to remediate this issue. See References for details. |
