Synopsis
The remote Ubuntu host is missing a security-related patch.
Description
David Benjamin discovered that OpenSSL did not correctly prevent buggy applications that ignore handshake errors from subsequently calling certain functions. (CVE-2017-3737)
It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery multiplication procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2017-3738).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected libssl1.0.0 package.
