VUL-1: CVE-2017-3732: openssl: BN_mod_exp may produce incorrect results on x86_64
Last modified: 2022-02-16 20:46:45 UTC
https://www.openssl.org/news/secadv/20170126.txt 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.

(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: https://bugzilla.suse.com/show_bug.cgi?id=957814#c0
