Critical vulnerabilities was discovered in Adobe Photoshop, which can be exploited by malicious people to compromise a user’s system.
The vulnerability is caused due to an error within the BMP.8BI Photoshop Format Plugin when handling Bitmap files (e.g. .BMP, .DIB, .RLE). This can be exploited to cause a stack-based buffer overflow via a specially crafted Bitmap file.
Successful exploitation allows execution of arbitrary code.The vulnerability is confirmed in Adobe Photoshop CS2 and reportedly affects Adobe Photoshop CS3. Other versions may also be affected.
It took less than a minute to download and install the patch so I encourage you to patch your copy of Photoshop. You can download the security patch from here.
Update: Also a Flash Player vulnerability was discovered recently.
Adobe recommends all users of Adobe Flash Player 9.0.45.0 and earlier versions upgrade to the newest version 9.0.47.0 (Win, Mac, Solaris) or 9.0.48.0 (Linux), by downloading it from the Player Download Center, or by using the auto-update mechanism within the product when prompted.
For customers who cannot upgrade to Adobe Flash Player 9, Adobe has developed a patched version of Flash Player 7. Please refer to the Flash Player update TechNote.
