Ubuntu 12.04 LTS : linux vulnerability (USN-2585-1)

low Nessus Plugin ID 83177

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that the Linux kernel's IPv6 networking stack has a flaw that allows using route advertisement (RA) messages to set the 'hop_limit' to values that are too low. An unprivileged attacker on a local network could exploit this flaw to cause a denial of service (IPv6 messages dropped).

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 packages.
