--- Comment #1 from Jeremy Harris <jgh146...@wizmail.org> ---
ZDI-CAN-17433 (Trend Micro)
A crafted SPA challenge from the server can cause the client authenticator
to read OOB; the data is then returned to the server.
Fix: validate the offset contained in the challenge, to avoid reading
past the end of the challenge data structure.
Vulnerable since at least 4.50, probably longer.
