--===============1311620249121452025== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="MZf7D3rAEoQgPanC" Content-Disposition: inline --MZf7D3rAEoQgPanC Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-4093-1 August 13, 2019 linux, linux-hwe, linux-azure, linux-gcp, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.04 - Ubuntu 18.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors - linux-hwe: Linux hardware enablement (HWE) kernel Details: It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10126) Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-1125) It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614) It was discovered that a NULL pointer dereference vulnerability existed in the Near-field communication (NFC) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-12984) Jann Horn discovered a use-after-free vulnerability in the Linux kernel when accessing LDT entries in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13233) Jann Horn discovered that the ptrace implementation in the Linux kernel did not properly record credentials in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2019-13272) It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-3846) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.04: linux-image-5.0.0-1013-gcp 5.0.0-1013.13 linux-image-5.0.0-1013-kvm 5.0.0-1013.14 linux-image-5.0.0-1014-azure 5.0.0-1014.14 linux-image-5.0.0-1014-raspi2 5.0.0-1014.14 linux-image-5.0.0-1018-snapdragon 5.0.0-1018.19 linux-image-5.0.0-25-generic 5.0.0-25.26 linux-image-5.0.0-25-generic-lpae 5.0.0-25.26 linux-image-5.0.0-25-lowlatency 5.0.0-25.26 linux-image-azure 5.0.0.1014.13 linux-image-gcp 5.0.0.1013.13 linux-image-generic 5.0.0.25.26 linux-image-generic-lpae 5.0.0.25.26 linux-image-gke 5.0.0.1013.13 linux-image-kvm 5.0.0.1013.13 linux-image-lowlatency 5.0.0.25.26 linux-image-raspi2 5.0.0.1014.11 linux-image-snapdragon 5.0.0.1018.11 linux-image-virtual 5.0.0.25.26 Ubuntu 18.04 LTS: linux-image-5.0.0-1014-azure 5.0.0-1014.14~18.04.1 linux-image-5.0.0-25-generic 5.0.0-25.26~18.04.1 linux-image-5.0.0-25-generic-lpae 5.0.0-25.26~18.04.1 linux-image-5.0.0-25-lowlatency 5.0.0-25.26~18.04.1 linux-image-azure 5.0.0.1014.25 linux-image-generic-hwe-18.04 5.0.0.25.82 linux-image-generic-lpae-hwe-18.04 5.0.0.25.82 linux-image-lowlatency-hwe-18.04 5.0.0.25.82 linux-image-snapdragon-hwe-18.04 5.0.0.25.82 linux-image-virtual-hwe-18.04 5.0.0.25.82 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.
