Description

Shadow mode tracing code uses a set of per-CPU variables to avoid<br /> cumbersome parameter passing. Some of these variables are written to<br /> with guest controlled data, of guest controllable size. That size can<br /> be larger than the variable, and bounding of the writes was missing.
