from SANS Internet Storm Center, InfoCON: green
Adobe did not release a patch for Flash on Tuesday, but instead alerted users of an unpatched, and actively exploited, vulnerability (CVE-2016-4171).
Today, Adobe did release a patch that fixes this vulnerability (and others). This is a "PATCH NOW" vulnerability that needs to be addressed as soon as possible.
