Vulnerability Description
A remote code execution vulnerability has been discovered in the way several Adobe products process PNG files. PNG (Portable Network Graphics) is a bitmapped image format that is used as an alternative to other image formats such as GIF and TIFF. By persuading a user to open a specially crafted PNG image file, an attacker may be able to execute arbitrary code on an affected system.
Vulnerability Details
The vulnerability is due to a boundary error in the PNG.8BI plugin in the Adobe Photoshop that fails to properly handle malformed PNG files. By convincing a user to visit a specially crafted HTML documents or open a malicious web page, a remote attacker could create a stack-based buffer overflow. Successful exploitation may allow execution of arbitrary code on a vulnerable system.
