Executive brief
A flaw in Windows' USB Video Driver could allow an authenticated attacker to overflow memory buffers and gain elevated administrative privileges on an affected system. This could lead to complete system compromise, including unauthorized access to sensitive corporate data or installation of malware with system-level permissions.
Technical details
A heap-based buffer overflow exists in the Windows USB Video Driver that can be triggered by an authenticated attacker. The vulnerability allows memory corruption that can be leveraged to achieve privilege escalation. While the advisory indicates the attack can occur "over a network," the requirement for prior authentication suggests a compromise of user credentials is a prerequisite. An attacker exploiting this flaw can gain SYSTEM-level privileges. Microsoft has released a security update to address this issue.
