The same security company that found a security flaw in Steam earlier this year has found security holes in Modern Warfare 3 and CryEngine 3.

As ComputerWorld reports , researchers from security company ReVuln announced their findings at a security conference in Seoul today. They demonstrated two major issues. The first was with Call of Duty: Modern Warfare 3 which, according to the presentation, is open to malicious denial of service (DDoS) attacks that can crash the game servers.

The other major issue was found in Crytek's CryEngine 3, and demonstrated on the game Nexuiz. The research team was able to access a remote player's computer via the game servers and "caused a graphic of cat riding a rocket to be displayed on the victim's computer."

If only all hackers sent cat pictures.

Of course, as a security company, it's in ReVuln's interest to point out security flaws, even minute ones, in any software they can. The company is planning to release full advisories about their findings next Tuesday, to coincide with the launch of the next Call of Duty game, Black Ops II.
