[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-2236-1 --- # USN-2236-1: Linux kernel (OMAP4) vulnerabilities Publication date 5 June 2014 Overview Several security issues were fixed in the kernel. Releases [12.04](https://ubuntu.com/security/notices?release=precise) --- Open side navigation ## Packages * [linux-ti-omap4](https://ubuntu.com/security/cves?package=linux-ti-omap4) - Linux kernel for OMAP4 ## Details Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. ([CVE-2014-3153](https://ubuntu.com/security/CVE-2014-3153)) A flaw was discovered in the vhost-net subsystem of the Linux kernel. Guest OS users could exploit this flaw to cause a denial of service (host OS crash). ([CVE-2014-0055](https://ubuntu.com/security/CVE-2014-0055)) Sasha Levin reported a bug in the Linux kernel's virtual memory management subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). ([CVE-2014-3122](https://ubuntu.com/security/CVE-2014-3122)) ## 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, 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-3.2.0-1449-omap4](https://launchpad.net/ubuntu/+source/linux-ti-omap4) –  [3.2.0-1449.68](https://launchpad.net/ubuntu/+source/linux-ti-omap4/3.2.0-1449.68) | | | --- ### 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.
