CVE-2016-7056 Open this link in a new tabHow to fix?
Upgrade OpenSSL
to version 1.0.211 or higher.
Overview
OpenSSL is a SSL/TLS and Crypto toolkit. Deprecated in Mac OS and gone in iOS, this spec gives your project non-deprecated OpenSSL support.
Affected versions of this package are vulnerable to Key Management Errors. OpenSSL is vulnerable to a cache-timing attack. The attack exists due to a flaw in signing function of crypto/ecdsa/ecdsa_ossl.c
which sets the BN_FLG_CONSTTIME
flag for nonces instead of taking a secure code path in the BN_mod_inverse
method.
