OpenSSL 1.1.0 < 1.1.0j Multiple Vulnerabilities
medium Nessus Plugin ID 121384
Language:
Synopsis
The remote service is affected by multiple vulnerabilities.Description
The version of OpenSSL installed on the remote host is prior to 1.1.0j. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.0j advisory.- The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). (CVE-2018-0734)
- The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.1.1a (Affected 1.1.1). (CVE-2018-0735)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to OpenSSL version 1.1.0j or later.See Also
