Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2643-2 advisory.

The Fix for CVE-2015-1328 introduced a regression into the Linux kernel's overlayfs file system. The removal of a directory that only exists on the lower layer results in a kernel panic.

We apologize for the inconvenience.
