Vulnerability in Canonical Display Driver Could Allow Remote Code Execution (2032276)
This security update resolves a publicly disclosed vulnerability in the Canonical Display Driver (cdd.dll). Although it is possible that the vulnerability could allow code execution, successful code execution is unlikely due to memory randomization. In most scenarios, it is much more likely that an attacker who successfully exploited this vulnerability could cause the affected system to stop responding and automatically restart.
