A new PNG buffer overflow vulnerability has surfaced ... While this is most likely proof-of-concept, untrusted PNG formats should not be used in Photoshop until this issue is patched.

Marsu has discovered a vulnerability in various Adobe Products, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to a boundary error within the PNG.8BI Photoshop Format Plugin when handling PNG files. This can be exploited to cause a stack-based buffer overflow via a specially crafted PNG file. Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in Adobe Photoshop CS2 and Adobe Photoshop Elements (Editor) version 5.0 for Windows and reportedly affects Adobe Photoshop CS3.
