Adobe Patches Flash Player Zero-Day Threat
Summary: Adobe issued an emergency patch for a critical Flash Player vulnerability present in all versions, including 21.0.0.197 and earlier, across Windows, Mac, Linux and Chrome OS. Adobe said the flaw was being actively exploited on Windows 7 and Windows XP systems running Flash Player 20.0.0.306 and earlier, and Trend Micro cited evidence thieves had used it in automated attacks since at least March 31, 2016.
Key Takeaway: The exploit was already in automated use before the patch shipped, and the protections in Flash 21.0.0.182 and newer only mitigated the flaw rather than fixing the underlying code - leaving every unpatched endpoint exposed to an attack that required no user judgment to succeed.
