Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3301-1 advisory.

 It was discovered that the strongSwan gmp plugin incorrectly validated RSA public keys. A remote attacker could use this issue to cause strongSwan to crash, resulting in a denial of service. (CVE-2017-9022)

 It was discovered that strongSwan incorrectly parsed ASN.1 CHOICE types. A remote attacker could use this issue to cause strongSwan to hang, resulting in a denial of service. (CVE-2017-9023)
