Who is Vulnerable?
Vulnerability Description Adobe Acrobat and Reader products include a plugin to parse the U3D image files inside PDF documents. The Universal 3D format can link to external image files, for example in PSD format, that provide texture data for the 3D objects. The .PSD (Photoshop Document), Adobe Photoshop's native format, stores an image with support for most imaging options available in Photoshop. A memory corruption vulnerability has been reported in Adobe Reader and Acrobat. The vulnerability is due to a 3D file parsing input validation error in Adobe Reader and Acrobat when parsing an external texture file in PSD format. A remote attacker could trigger this issue via a specially crafted PSD file that uses run-length encoding for its pixel data. Successful exploitation will create a denial of service condition, causing the application to become non-responsive, and may allow execution of arbitrary code once a malicious file is loaded on a vulnerable system.
