|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 BMP format, that provide texture data for the 3D objects. BMP is an image file format used to store bitmap digital images.A buffer overflow vulnerability has been reported in Adobe Reader and Acrobat.The vulnerability is due to an image parsing input validation error in Adobe Reader and Acrobat when parsing an external texture file in BMP format. A remote attacker could trigger this issue via a specially crafted BMP file. 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.|
This protection will detect and block attempts to transfer malformed BMP files over HTTP.
