An error occurs in the elliptic curve point addition algorithm that uses
mixed Jacobian-affine coordinates where it can yield a result
“POINT_AT_INFINITY” when it should not. A man-in-the-middle attacker could
use this to interfere with a connection, resulting in an attacked party
computing an incorrect shared secret. This vulnerability affects Firefox <
55.
