Enlarge (credit: Lisa Brewster / Flickr) Microsoft on Tuesday patched two Windows vulnerabilities that attackers are actively exploiting in the wild to install malicious apps on the computers of unwitting users.The first vulnerability resides in the VBScript Engine included in all currently supported versions of Windows.
