A vulnerability in the handling of functions available through the Extended Stored Procedures API may allow an attacker to overflow a fixed length buffer and execute code of their choosing on an affected host. A DoS condition may also result due to the server failing to handle a memory copy routine properly which may cause the server to crash. In particular this rule generates an event when an attempt is made to exploit the function "xp_oasetproperty". Ease of Attack: Simple. Exploit code exists.
