The DebugDiag ActiveX control in CrashHangExt.dll, possibly 1.0, in Microsoft Debug Diagnostic Tool allows remote attackers to cause a denial of service (NULL pointer dereference and Internet Explorer 6.0 crash) via a large negative integer argument to the GetEntryPointForThread method. NOTE: this issue might only be exploitable in limited environments or non-default browser settings.

Security readout for executives and security teams

This CVE describes a crash condition in a DebugDiag ActiveX control used by Microsoft Debug Diagnostic Tool. If reachable through Internet Explorer 6 in certain settings, a remote attacker could crash the browser, causing denial of service. The source bundle notes exposure may be limited to non-default or unusual browser configurations. Likely limited to legacy workstations with Microsoft Debug Diagnostic Tool, the CrashHangExt.dll ActiveX control, and browser settings that permit the control to load in Internet Explorer 6. Treat as a legacy hygiene issue unless the organization still runs IE6-era ActiveX workflows. Business urgency is low for modern environments, but any confirmed legacy exposure should be removed or isolated because browser crashes can disrupt affected users. Mitigation focus: Check Microsoft guidance for Debug Diagnostic Tool and CrashHangExt.dll before applying vendor-specific fixes.; Inventory systems for DebugDiag and CrashHangExt.dll, especially legacy Internet Explorer environments.; Disable or remove unnecessary DebugDiag ActiveX exposure where operationally safe..
