Adobe has issued a security patch for its Adobe Photoshop CS4 software to plug critical vulnerabilities that expose users to code execution attacks with rigged image files. The flaws affect both Windows and Mac OS X users. Adobe Photoshop Photoshop CS5 is not affected by these issues. The company recommends that users update to Adobe CS4 11.0.2, which resolves these issues, to avoid the risks of an attacker taking complete control of the affected system with a malicious image file must be opened by the user.
