Integer signedness error in system/core/adb/adb_client.c in Android Debug Bridge (ADB) for Android 4.4 in the Android SDK Platform Tools 18.0.1 allows ADB servers to execute arbitrary code via a negative length value, which bypasses a signed comparison and triggers a stack-based buffer overflow.

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.
