Immediately after informing us about the availability of a new kernel update for the Ubuntu 16.04 LTS (Xenial Xerus) operating system, Canonical published more security advisories about updated kernel versions for Ubuntu 14.04 LTS and Ubuntu 12.04 LTS.

Ubuntu 16.04 LTS is not the only operating system for which Canonical releases updated kernels that patch various security flaws discovered recently upstream by Linux kernel developers, and Ubuntu Security Notice USN-3071-1 and Ubuntu Security Notice USN-3072-1 contain details about what's new in today's updates.

According to these security notices, it appears that a total of five kernel vulnerabilities have been addressed in the kernel packages of Ubuntu 14.04 LTS (Trusty Tahr), and three in those of Ubuntu 12.04 LTS (Precise Pangolin), and users are urged to update their PCs immediately.

There are fixes for an information leak in Linux kernel's Reliable Datagram Sockets (RDS) implementation, a heap-based buffer overflow in the USB HID driver, a flaw in the TCP (Transmission Control Protocol) implementation, a race condition in the MIC VOP driver, and some issues with PowerPC platforms.

As expected, Canonical urges all users of the Ubuntu 14.04 LTS (Trusty Tahr) and Ubuntu 12.04 LTS (Precise Pangolin) operating systems, as well as any supported derivative to update their systems to linux-image-3.13.0-95 (3.13.0-95.142) and linux-image-3.2.0-109 (3.2.0-109.150) as soon as possible.

Of course, if you're using Ubuntu 12.04.5 LTS or Ubuntu 14.04.5 LTS, you'll get updated kernels too, but different versions. To update your system check out the instructions available at https://wiki.ubuntu.com/Security/Upgrades, and don't forget to reboot your computer after the new kernel was installed.
