Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5002-1 advisory.

 Norbert Slusarek discovered a race condition in the CAN BCM networking protocol of the Linux kernel leading to multiple use-after-free vulnerabilities. A local attacker could use this issue to execute arbitrary code.
