BN_mod_exp may produce incorrect results on x86_64 (CVE-2017-3732)
==================================================================

Severity: Moderate

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.

OpenSSL 1.1.0 users should upgrade to 1.1.0d
OpenSSL 1.0.2 users should upgrade to 1.0.2k

This issue was reported to OpenSSL on 15th January 2017 by the OSS-Fuzz project.
The fix was developed by Andy Polyakov of the OpenSSL development team.

Comment 3 Vítězslav Čížek 2017-01-31 14:19:34 UTC
(In reply to Andreas Stieger from comment #1)
> This is in 1.0.1, not before.
I don't think 1.0.1 is affected. The montgomery reduction part was introduced in https://git.openssl.org/?p=openssl.git;a=commit;h=ec9cc70f72454b8d4a84247c86159613cee83b81
The code hasn't ever gotten to 1.0.1 branch.

The x86_64-mont.pl alternative (CVE-2015-3193) was also 1.0.2 only:
