CVE-2016-2178 Open this link in a new tabHow to fix?
Upgrade RHEL:7 openssl to version 1:1.0.1e-51.el7_2.7 or higher.
This issue was patched in RHSA-2016:1940.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.
