This critical vulnerability is a heap buffer overflow vulnerability (CVE-2015-3113) that is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer, as well as XP machines running Firefox, are known targets according to Adobe. If this vulnerability is exploited, an attacker could remotely execute code on unpatched machines.
MiWorkspace machines will be patched as soon as possible. If you have Adobe Flash Player installed on your own devices that are not managed by the university, please update it by visiting the Adobe Flash Player Download Center.
In general, the best protection for your devices is this: keep your software and apps up-to-date, do not click suspicious links in email, do not open email attachments unless you are expecting them and trust the person who sent them, and only use secure, trusted networks. For more information, see Spam, Phishing, and Suspicious Email, Instructions for Securing Your Devices and Data, and Use a Secure Internet Connection.
