# Unspecified vulnerability in the U3D component in Adobe Reader and Acrobat 10.1.1 and earlier on Windows and Mac OS…

Adobe Reader and Acrobat contain a memory corruption flaw in the Universal 3D (U3D) component. A remote attacker can run code or crash the application by getting a victim to open a crafted file.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Unspecified vulnerability in the U3D component in Adobe Reader and Acrobat 10.1.1 and earlier on Windows and Mac OS X, and Adobe Reader 9.x through 9.4.6 on UNIX, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unknown vectors, as exploited in the wild in December 2011.
