This is caused by a bug in the handling of the ASN.1 CHOICE + type in OpenSSL 1.1.0 which can result in a NULL value being passed to the + structure callback if an attempt is made to free certain invalid encodings. + Only CHOICE structures using a callback which do not handle NULL value are + affected. + + This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure. + (CVE-2016-7053) + [Stephen Henson] + + *) Montgomery multiplication may produce incorrect results + + There is a carry propagating bug in the Broadwell-specific Montgomery + multiplication procedure that handles input lengths divisible by, but + longer than 256 bits. Analysis suggests that attacks against RSA, DSA + and DH private keys are impossible. This is because the subroutine in + question is not used in operations with the private key itself and an input + of the attacker's direct choice. Otherwise the bug can manifest itself as + transient authentication and key negotiation failures or reproducible + erroneous outcome of public-key operations with specially crafted input. + Among EC algorithms only Brainpool P-512 curves are affected and one + presumably can attack ECDH key negotiation. Impact was not analyzed in + detail, because pre-requisites for attack are considered unlikely. Namely + multiple clients have to choose the curve in question and the server has to + share the private key among them, neither of which is default behaviour. + Even then only clients that chose the curve will be affected. + + This issue was publicly reported as transient failures and was not + initially recognized as a security issue.
