Two citical updates for Windows released
MS15-056 updated Internet Explorer and fixed 24 vulnerabilities by “preventing browser histories from being accessed by a malicious site,” as well as “adding additional permission validations to Internet Explorer [and] modifying how Internet Explorer handles objects in memory,” the release said, noting that “customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
MS15-057 plugged a hole in Windows with which attackers could seize control remotely of a system if Windows Media Player “opens specially crafted media content that is hosted on a malicious website.”
These patches should be installed on all systems and are available from Windows Update. Inaddition to these Microsoft has released six non-critical updates.
