[Disclosure Timeline]
An elevation of privilege vulnerability exists in Windows when the
Win32k component fails to properly handle objects in memory. An
attacker who successfully exploited this vulnerability could run
arbitrary code in kernel mode. An attacker could then install
programs; view, change, or delete data; or create new accounts with
full user rights.
To exploit this vulnerability, an attacker would first have to log on
to the system. An attacker could then run a specially crafted
application that could exploit the vulnerability and take control of
an affected system.
The update addresses this vulnerability by correcting how Win32k
handles objects in memory.
