Critical Vulnerability in Adobe Flash Being Actively Exploited
Date: 02 February 2015
The purpose of this Alert is to bring attention to a recently published Critical Security Advisory for Adobe Flash Player.
CCIRC is aware of several popular websites which have been re-directing users to websites serving a malicious .swf file exploiting a critical vulnerability in Adobe Flash. Malicious ad re-direction or Malvertising is serving an exploit, identified as CVE-2015-0313, which affects the most recent version of Adobe Flash. When the user is redirected to the compromised site, they are automatically infected with no further input or interaction with the user. Successful exploitation could potentially allow an attacker to take control of the affected system.
Adobe Flash Player 126.96.36.1996 and earlier versions for Windows and Macintosh
Adobe Flash Player 188.8.131.524 and earlier 13.x versions
Adobe Flash Player 184.108.40.2060 and earlier versions for Linux
Adobe is expected to release an updated version of Flash later this week. Organizations should prioritize implementation of this update when available.
