Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
A flaw was discovered in the Linux kernel's pseudo tty (pty) device.
An unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrator privileges.
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 linux-image-3.11-generic and / or linux-image-3.11-generic-lpae packages.
