Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : strongswan vulnerability (USN-3774-1)
High Nessus Plugin ID 117868
Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
It was discovered that strongSwan incorrectly handled signature validation in the gmp plugin. A remote attacker could use this issue to cause strongSwan to crash, resulting in a denial of service, or possibly execute arbitrary code.
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 libstrongswan and / or strongswan packages.
