Microsoft warns of vulnerability being targeted in Internet Explorer: SSO Alert Priority High
28 April 2014
Microsoft has issued a security advisory warning about a critical vulnerability affecting all versions of Internet Explorer.
The vulnerability is known to be targeted by cyber criminals. You should take action to ensure you will not be affected.
The vulnerability could be exploited if an attacker can gain access to your computer, or if you visit a malicious website using one of the affected versions of Internet Explorer.
Microsoft advises that it is currently investigating the issue and will take appropriate action (such as releasing a patch) as soon as possible. In the meantime it suggests a work around for users who wish to continue using Internet Explorer. This includes deploying the Enhanced Mitigation Experience Toolkit (EMET) or by setting your Internet Explorer ‘Security Zone’ settings to ‘High’.
You can find this in Tools > Internet Options > Security tab. Changing your Security Zone to high may affect your ability to access components of some websites.
A more simple alternative solution is to download and install a different browser such as Google Chrome or Mozilla Firefox until this issue is resolved.
