Ubuntu 14.04 LTS : linux-lts-vivid vulnerability (USN-2718-1)

medium Nessus Plugin ID 85511
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Marcelo Ricardo Leitner discovered a race condition in the Linux kernel's SCTP address configuration lists when using Address Configuration Change (ASCONF) options on a socket. An unprivileged local user could exploit this flaw to cause a denial of service (system crash).

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-3.19-generic, linux-image-3.19-generic-lpae and / or linux-image-3.19-lowlatency packages.
