Integer underflow in the CDownloadSink class code in the Vector Markup Language (VML) component (VGX.DLL), as used in Internet Explorer 5.01, 6, and 7 allows remote attackers to execute arbitrary code via compressed content with an invalid buffer size, which triggers a heap-based buffer overflow.

Security readout for executives and security teams

This is a legacy Internet Explorer flaw in Microsoft’s VML component. A malicious web page or similar browser-delivered content could trigger memory corruption and potentially run attacker-controlled code. The concern is highest for organizations that still have old Internet Explorer 5.01, 6, or 7 systems in use. Exposure is likely limited to legacy environments running the affected Internet Explorer versions or systems retaining vulnerable VGX.DLL/VML handling. Modern supported browsers are not named in the source bundle, so current exposure should be confirmed by asset inventory rather than assumed. Treat this as a legacy technology risk. It is serious where old Internet Explorer remains in production, but urgency depends on whether those systems can reach untrusted content. The practical priority is finding and eliminating remaining legacy browser dependencies. Mitigation focus: Apply Microsoft guidance and updates from MS07-050 where applicable.; Retire or isolate systems requiring Internet Explorer 5.01, 6, or 7.; Disable or restrict legacy VML handling where vendor guidance supports it..
