This could be exploited in a Denial + of Service attack. + + This issue was reported to OpenSSL by Guido Vranken. + (CVE-2017-3730) + [Matt Caswell] + + *) BN_mod_exp may produce incorrect results on x86_64 + + There is a carry propagating bug in the x86_64 Montgomery squaring + procedure. 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. 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. For example this can occur by + default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very + similar to CVE-2015-3193 but must be treated as a separate problem. + + This issue was reported to OpenSSL by the OSS-Fuzz project. + (CVE-2017-3732) + [Andy Polyakov] Changes between 1.1.0b and 1.1.0c [10 Nov 2016] diff --git a/NEWS b/NEWS index 929794e5c0..06214a0cbf 100644 --- a/NEWS +++ b/NEWS @@ -7,7 +7,9 @@ Major changes between OpenSSL 1.1.0c and OpenSSL 1.1.0d [under development] - o + o Truncated packet could crash via OOB read (CVE-2017-3731) + o Bad (EC)DHE parameters cause a client crash (CVE-2017-3730) + o BN_mod_exp may produce incorrect results on x86_64 (CVE-2017-3732) Major changes between OpenSSL 1.1.0b and OpenSSL 1.1.0c [10 Nov 2016]
