The internal Point.of octets function is missing a length check for compressed points, and thus is raising an exception when a short buffer is provided. This affects all NIST curves (P-256, P-384, P-521) and both Dsa.pub of octets and Dh.key exchange functions.

Fix

The fix is to check the length of the provided buffer.
