Earlier this week, French malware researcher Kafeine reported on a new Adobe Flash zero-day vulnerability that was being exploited in the wild using the latest versions of the Angler Exploit Toolkit.
"Any version of Internet Explorer or Firefox with any version of Windows will get owned if Flash up to 16.0.0.287 (included) is installed and enabled" said Kafeine. While Windows platforms seem to be the current target, it's plausible to assume that Macintosh and Linux systems may soon be targeted as well.
Today, Adobe addressed the zero-day flaw by releasing a security patch for all supported software platforms. The patch fixes CVE-2015-0310 and brings Flash Player versions up to 16.0.0.287 for Windows and Macintosh and 11.2.202.438 for Linux.
According to Adobe's Product Security Incident Response Team blog, however, another separate exploit that works against the latest 16.0.0.287 version released today may exist in the wild:
"Adobe is aware of reports that an exploit for CVE-2015-0310 exists in the wild, which is being used in attacks against older versions of Flash Player. Additionally, we are investigating a report that a separate exploit for Flash Player 16.0.0.287 and earlier versions also exists in the wild. Please continue to monitor this blog for updates."
Even customers who apply the patches listed in today's APSB15-02 security bulletin should remain cautious due to the uncertainty of the validity of this new exploit. Retina and BeyondInsight customers can use the following audits (available in audits release 2870 or higher) to help ensure that the Flash patches have been applied across their network:

44637 - Adobe APSB15-02: Flash Player - IE for Windows XP/2003/Vista/2008/7
44640 - Adobe APSB15-02: Flash Player - Mac OS X
44641 - Adobe APSB15-02: Flash Player - Other browsers for Windows
