Ubuntu 14.04 LTS / 16.04 LTS / 17.10 : openssl vulnerability (USN-3628-1)

Medium Nessus Plugin ID 109200

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Alejandro Cabrera Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis Manuel Alvarez Tapia discovered that OpenSSL incorrectly handled RSA key generation. An attacker could possibly use this issue to perform a cache-timing attack and recover private RSA keys.

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.
