Unspecified vulnerability in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, and Windows 7 through SP1 allows attackers to bypass the ASLR protection mechanism via unknown vectors, as demonstrated against Adobe Flash Player by VUPEN during a Pwn2Own competition at CanSecWest 2013, aka "ASLR Security Feature Bypass Vulnerability."

Security readout for executives and security teams

This is a Microsoft Windows ASLR bypass affecting Windows Vista SP2, Windows Server 2008 SP2/R2 SP1, and Windows 7 through SP1. It weakens a key exploit mitigation rather than directly providing code execution. Business urgency comes from chaining: attackers can use ASLR bypasses to make other memory-corruption exploits more reliable. Exposure is most likely on legacy Windows Vista, Windows 7 SP1 or earlier, and Windows Server 2008 SP2/R2 SP1 systems missing Microsoft MS13-063 or equivalent successor guidance. Treat as a legacy exposure cleanup item with elevated priority where affected systems handle untrusted content or run browser plugins. It is not documented here as actively exploited. Mitigation focus: Review Microsoft MS13-063 and apply the vendor-recommended update path.; Inventory affected Windows versions across endpoints and servers.; Isolate or retire systems where vendor remediation is unavailable..
