CVE-2015-4435: Adobe Reader and Acrobat 10.x before 10.1.15 and 11.x before 11.0.12, Acrobat and Acrobat Reader DC Classic...

Security readout for executives and security teams

CVE-2015-4435 affects older Adobe Reader and Acrobat releases on Windows and OS X. It allowed attackers to bypass JavaScript API execution restrictions through unspecified vectors. The sources do not describe direct code execution, data theft, or active exploitation, but the issue weakens a security boundary in widely used PDF software. Exposure is most likely on endpoints still running the listed pre-fix Adobe Reader or Acrobat versions, especially systems that open untrusted PDFs. The source bundle does not identify server-side exposure, mobile products, browser-only components, or non-Adobe PDF readers as affected. Treat this as a legacy endpoint hygiene issue unless affected versions remain in use. If old Adobe Reader or Acrobat installations are present, remediation should be scheduled promptly because PDF handling is commonly exposed to untrusted content. Mitigation focus: Apply Adobe APSB15-15 updates or later fixed Reader and Acrobat versions.; Prioritize systems that open external or email-delivered PDF files.; Remove or replace affected Adobe Reader and Acrobat versions where updates cannot be applied..
