A French security researcher has revealed a flaw in the handling of Bitmap files within Adobe's Photoshop program that can lead to an exploit of a user's system.
According to the researcher, known as Marsu, a buffer overflow in Adobe products can be triggered while processing a malformed BMP, DIB or RLE file.
Affected programs include Adobe Photoshop CS2 and CS3, says the researcher. The exploit was tested against the French Edition of Windows XP SP2.
Danish security research company Secunia said the solution is simple: "Do not open untrusted Bitmap files."
