Saturday, April 26, 2014

A serious vulnerability in Internet Explorer (IE) versions 6 through 11 allowing an attacker to gain control of a computer and can lead to data and password theft was recently reported. At this writing, Microsoft has not issued a patch for the problem.

UNH users should quickly take the following actions to reduce their risk until such time as a patch becomes available. Based on university user feedback and IT assessments, the recommended actions to reduce risk are:

Disable the Adobe Flash plug-in for IE (most important)Use Internet Explorer only to access UNH Enterprise systems such as Banner and Blackboard. UNH Enterprise systems are listed at here.· Use alternative browsers such as Firefox, Chrome or Safari to access websites and applications other than UNH Enterprise systems· Use a non-administrative account to browse the Internet

UNH users should update their IE version to at least IE 9. Depending on what UNH systems you access, you may be able to update to the latest versions, IE 10 and IE 11. You should also ensure your operating system and antivirus updates are set to automatic. Contact your IT support for assistance in evaluating and activating work-arounds and updates appropriate to your work and system access.

Microsoft security advisory dated April 26, 2014 identifies a number of mitigations and further work-arounds which reduce exposure to possible exploits.
