Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: USN-3742-2 introduced regressions in the Linux Hardware Enablement (HWE) kernel for Ubuntu 12.04 ESM. Software Description: - linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM Details: USN-3742-2 introduced mitigations in the Linux Hardware Enablement (HWE) kernel for Ubuntu 12.04 ESM to address L1 Terminal Fault (L1TF) vulnerabilities (CVE-2018-3620, CVE-2018-3646). Unfortunately, the update introduced regressions that caused kernel panics when booting in some environments as well as preventing Java applications from starting. This update fixes the problems. We apologize for the inconvenience. Original advisory details: It was discovered that memory present in the L1 data cache of an Intel CPU It was discovered that memory present in the L1 data cache of an Intel CPU Andrey Konovalov discovered an out-of-bounds read in the POSIX Juha-Matti Tilli discovered that the TCP implementation in the Linux kernel Juha-Matti Tilli discovered that the IP implementation in the Linux kernel Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: 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.
