(Red Hat Issues Fix) OpenSSL bn_sqrx8x_internal() Carry Bug Lets Remote Users Obtain Potentially Sensitive Information on the Target System in Certain Cases
SecurityTracker Alert ID:  1040677
SecurityTracker URL:  http://securitytracker.com/id/1040677
CVE Reference:   CVE-2017-3736   (Links to External Site)
Date:  Apr 13 2018
Impact:   Disclosure of authentication information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in OpenSSL. A remote user can obtain potentially sensitive information on the target system in certain cases.

A remote user can exploit a carry propagation flaw in the the x86_64 Montgomery squaring function bn_sqrx8x_internal() to potentially determine information about the private key in certain situations.

Processors that support the BMI1, BMI2, and ADX extensions (e.g., Intel Broadwell 5th generation and later, AMD Ryzen) are affected.

EC algorithms are not affected.

The Google OSS-Fuzz project reported this vulnerability.

Impact:   A remote user can potentially determine information about the private key in certain situations.
Solution:   Red Hat has issued a fix.
