[CVE-2017-3737]</p> + <p>There is an overflow bug in the x86_64 Montgomery + multiplication procedure used in exponentiation with 1024-bit + moduli.

[CVE-2017-3737]</p> + <p>Mishandling of carry propagation will produce incorrect + output, and make it easier for a remote attacker to obtain + sensitive private-key information.

The amount of resources required for such an attack + would be very significant and likely only accessible to a + limited number of attackers. However, for an attack on TLS + to be meaningful, the server would have to share the DH1024 + private key among multiple clients, which is no longer an + option since CVE-2016-0701.
