KEVEXPLOIT ✓HIGH 8.8EPSS 83.2%

Does this matter?

Known to be exploited in the wild (CISA KEV, CISA remediation deadline 22 June 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.

Description

The U3D implementation in Adobe Reader and Acrobat 9.x before 9.3, 8.x before 8.2 on Windows and Mac OS X, and 7.x before 7.1.4 allows remote attackers to execute arbitrary code via malformed U3D data in a PDF document, related to a CLODProgressiveMeshDeclaration "array boundary issue," a different vulnerability than CVE-2009-2994.
