DescriptionCVE.org

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.

AnalysisAI

Adobe Reader and Acrobat contain an unspecified U3D component vulnerability causing memory corruption that allows remote code execution, exploited as a zero-day in December 2011 through crafted PDF files.

Technical ContextAI

The CWE-787 memory corruption flaw in the U3D parsing component is triggered when Adobe Reader processes PDF files containing malformed 3D content. The corruption allows arbitrary code execution in the context of the Reader process.

RemediationAI

Update Adobe Reader/Acrobat. Disable 3D content rendering in Adobe Reader's preferences. Deploy sandboxed PDF readers or use browser-native PDF viewing.
