+ <h1>Problem Description:</h1>
+ <p>The implementation of lib9p's handling of RWALK messages was
+ missing a bounds check needed when unpacking the message contents.
+ The missing check means that the receipt of a specially crafted
+ message will cause lib9p to overwrite unrelated memory.</p>
+ <h1>Impact:</h1>
+ <p>The bug can be triggered by a malicious bhyve guest kernel to
+ overwrite memory in the bhyve(8) process. This could potentially lead
+ to user-mode code execution on the host, subject to bhyve's Capsicum
+ sandbox.</p>
