[CVE-2017-3735]</p> + <p>Mishandling of carry propagation will produce incorrect + output, and make it easier for a remote attacker to obtain + sensitive private-key information. No EC algorithms are + affected, analysis suggests that attacks against RSA and + DSA as a result of this defect would be very difficult to + perform and are not believed likely.</p> + <p>Attacks against DH are considered just feasible (although + very difficult) because most of the work necessary to deduce + information about a private key may be performed offline. + The amount of resources required for such an attack would + be very significant and likely only accessible to a limited + number of attackers. An attacker would additionally need + online access to an unpatched system using the target private + key in a scenario with persistent DH parameters and a private + key that is shared between multiple clients.
