RISK: Medium Risk

TYPE: Operating Systems - Windows OS

Win32k Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists due to the way the Windows kernel-mode driver handles 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 complete control over an affected system.
Win32k Information Disclosure Vulnerability
An information disclosure vulnerability exists when the Windows kernel-mode driver improperly handles certain non-initialized values in memory. An attacker who successfully exploited this vulnerability could leak memory addresses or other sensitive kernel information that could be used for further exploitation of the system.
