CVE-2016-4102: Use-after-free vulnerability in Adobe Reader and Acrobat before 11.0.16, Acrobat and Acrobat Reader DC Clas...

Security readout for executives and security teams

CVE-2016-4102 is a memory safety flaw in older Adobe Reader and Acrobat versions for Windows and OS X. If successfully triggered, it could let an attacker run code in the context of the user opening the content. Adobe addressed it in APSB16-14. No provided source shows active exploitation. Exposure is most likely on endpoints still running the affected Adobe Reader or Acrobat versions, especially where users open PDFs from email, browsers, file shares, or external sources. Modern, fully updated installations should not be affected according to the listed fixed versions. Treat as a high-priority legacy software cleanup issue. The business risk is code execution through a widely used document application, but urgency is highest where outdated Adobe software remains deployed. Confirm patch status rather than assuming this 2016 issue is gone. Mitigation focus: Update Adobe Reader and Acrobat to the APSB16-14 fixed versions or later.; Prioritize Windows and OS X endpoints with legacy Adobe Reader or Acrobat installations.; Remove unsupported or unnecessary Adobe Reader and Acrobat installations..
