+
+   Use of the low-level GF(2^m) elliptic curve APIs with untrusted
+   explicit values for the field polynomial can lead to out-of-bounds memory
+   reads or writes.
+   Applications working with "exotic" explicit binary (GF(2^m)) curve
+   parameters, that make it possible to represent invalid field polynomials
+   with a zero constant term, via the above or similar APIs, may terminate
+   abruptly as a result of reading or writing outside of array bounds. Remote
+   code execution cannot easily be ruled out.
