USN-3583-2 --- # USN-3583-2: Linux kernel (Trusty HWE) vulnerabilities Publication date 23 February 2018 Overview Several security issues were fixed in the Linux kernel. Releases [12.04](https://ubuntu.com/security/notices?release=precise) --- Open side navigation ## Packages * [linux-lts-trusty](https://ubuntu.com/security/cves?package=linux-lts-trusty) - Linux hardware enablement kernel from Trusty for Precise ESM ## Details USN-3583-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 ESM. It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System (f2fs) in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. ([CVE-2017-0750](https://ubuntu.com/security/CVE-2017-0750)) It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. ([CVE-2017-0861](https://ubuntu.com/security/CVE-2017-0861)) It was discovered that the KVM implementation in the Linux kernel... --- Show more ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 12.04 precise | [linux-image-3.13.0-142-generic](https://launchpad.net/ubuntu/+source/linux-lts-trusty) –  [3.13.0-142.191~precise1](https://launchpad.net/ubuntu/+source/linux-lts-trusty/3.13.0-142.191~precise1) | | | | [linux-image-generic-lpae-lts-trusty](https://launchpad.net/ubuntu/+source/linux-lts-trusty) –  [3.13.0.142.133](https://launchpad.net/ubuntu/+source/linux-lts-trusty/3.13.0-142.191~precise1) | | | | [linux-image-3.13.0-142-generic-lpae](https://launchpad.net/ubuntu/+source/linux-lts-trusty) –  [3.13.0-142.191~precise1](https://launchpad.net/ubuntu/+source/linux-lts-trusty/3.13.0-142.191~precise1) | | | | [linux-image-generic-lts-trusty](https://launchpad.net/ubuntu/+source/linux-lts-trusty) –  [3.13.0.142.133](https://launchpad.net/ubuntu/+source/linux-lts-trusty/3.13.0-142.191~precise1) | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
