========================================================================== Ubuntu Security Notice USN-3908-2 March 13, 2019
linux-lts-trusty vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 ESM
Summary:
The system could be made to run programs as an administrator.
Software Description: - linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM
Details:
USN-3908-1 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.
Jann Horn discovered a race condition in the fork() system call in the Linux kernel. A local attacker could use this to gain access to services that cache authorizations.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 ESM: linux-image-3.13.0-166-generic 3.13.0-166.216~precise1 linux-image-3.13.0-166-generic-lpae 3.13.0-166.216~precise1 linux-image-3.13.0-166-lowlatency 3.13.0-166.216~precise1 linux-image-generic-lpae-lts-trusty 3.13.0.166.156 linux-image-generic-lts-trusty 3.13.0.166.156
After a standard system update you need to reboot your computer to make all the necessary changes.
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.
