Vulnerability Information
Win32k Improper Message Handling Vulnerability - CVE-2013-0008
An elevation of privilege vulnerability exists when the Windows kernel
improperly handles window broadcast messages. An attacker who successfully
exploited this vulnerability could take complete control of an affected
system. An attacker could then install programs; view, change, or delete data;
or create new accounts with full user rights. Users whose accounts are
configured to have fewer user rights on the system could be less impacted than
users who operate with administrative user rights.
