The remote host is affected by the vulnerability described in GLSA-201612-16 (OpenSSL: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers and the International Association for Cryptologic Research’s (IACR) paper, “Make Sure DSA Signing Exponentiations Really are Constant-Time” for further details.
Impact :
Remote attackers could cause a Denial of Service condition or have other unspecified impacts. Additionally, a time based side-channel attack may allow a local attacker to recover a private DSA key.
Workaround :
There is no known workaround at this time.
