CVE-2018-3646

TITLE

Intel processors are vulnerable to a speculative execution side-channel attack called L1 Terminal Fault (L1TF)

DESCRIPTION

Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis. These attacks are known as L1 Terminal Fault: SGX, L1 Terminal Fault: OS/SMM, and L1 Terminal Fault: VMM. Intel Core Systems with microprocessors contain information disclosure vulnerabilities.Information may be obtained. Intel Core i3 processor, etc. are all CPU (central processing unit) products of Intel Corporation of the United States. Security vulnerabilities exist in several Intel products that use speculative execution and address translation. The following products are affected: Intel Core i3 processor; Intel Core i5 processor; Intel Core i7 processor; Intel Core M processor family; 2nd generation Intel Core processors; 3rd generation Intel Core processors; 4th generation Intel Core processors; 5th generation Intel Core processors, etc. ========================================================================= Ubuntu Security Notice USN-3742-1 August 14, 2018 linux vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the Linux kernel. A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). (CVE-2018-3646) It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. (CVE-2018-3620) Andrey Konovalov discovered an out-of-bounds read in the POSIX timers subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2017-18344) Juha-Matti Tilli discovered that the TCP implementation in the Linux kernel performed algorithmically expensive operations in some situations when handling incoming packets. A remote attacker could use this to cause a denial of service. (CVE-2018-5390) Juha-Matti Tilli discovered that the IP implementation in the Linux kernel performed algorithmically expensive operations in some situations when handling incoming packet fragments. A remote attacker could use this to cause a denial of service. (CVE-2018-5391) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.13.0-155-generic 3.13.0-155.205 linux-image-3.13.0-155-generic-lpae 3.13.0-155.205 linux-image-3.13.0-155-lowlatency 3.13.0-155.205 linux-image-3.13.0-155-powerpc-e500 3.13.0-155.205 linux-image-3.13.0-155-powerpc-e500mc 3.13.0-155.205 linux-image-3.13.0-155-powerpc-smp 3.13.0-155.205 linux-image-3.13.0-155-powerpc64-emb 3.13.0-155.205 linux-image-3.13.0-155-powerpc64-smp 3.13.0-155.205 linux-image-generic 3.13.0.155.165 linux-image-generic-lpae 3.13.0.155.165 linux-image-lowlatency 3.13.0.155.165 linux-image-powerpc-e500 3.13.0.155.165 linux-image-powerpc-e500mc 3.13.0.155.165 linux-image-powerpc-smp 3.13.0.155.165 linux-image-powerpc64-emb 3.13.0.155.165 linux-image-powerpc64-smp 3.13.0.155.165 Please note that the recommended mitigation for CVE-2018-3646 involves updating processor microcode in addition to updating the kernel; however, the kernel includes a fallback for processors that have not received microcode updates. 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 microcode updates mentioned there are not yet available in a form distributable by Debian. For the stable distribution (stretch), these problems have been fixed in version 4.8.4+xsa273+shim4.10.1+xsa273-1+deb9u10. We recommend that you upgrade your xen packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2018-10-30-9 Additional information for APPLE-SA-2018-9-24-1 macOS Mojave 10.14 macOS Mojave 10.14 addresses the following: Bluetooth Available for: iMac (21.5-inch, Late 2012), iMac (27-inch, Late 2012) , iMac (21.5-inch, Late 2013), iMac (21.5-inch, Mid 2014), iMac (Retina 5K, 27-inch, Late 2014), iMac (21.5-inch, Late 2015), Mac mini (Mid 2011), Mac mini Server (Mid 2011), Mac mini (Late 2012) , Mac mini Server (Late 2012), Mac mini (Late 2014), Mac Pro (Late 2013), MacBook Air (11-inch, Mid 2011), MacBook Air (13-inch, Mid 2011), MacBook Air (11-inch, Mid 2012), MacBook Air (13-inch, Mid 2012), MacBook Air (11-inch, Mid 2013), MacBook Air (13-inch, Mid 2013), MacBook Air (11-inch, Early 2015), MacBook Air (13-inch, Early 2015), MacBook Pro (13-inch, Mid 2012), MacBook Pro (15-inch, Mid 2012), MacBook Pro (Retina, 13-inch, Early 2013), MacBook Pro (Retina, 15-inch, Early 2013), MacBook Pro (Retina, 13-inch, Late 2013), and MacBook Pro (Retina, 15-inch, Late 2013) Impact: An attacker in a privileged network position may be able to intercept Bluetooth traffic Description: An input validation issue existed in Bluetooth.

Summary: An update for kernel is now available for Red Hat Enterprise Linux 6.6 Advanced Update Support and Red Hat Enterprise Linux 6.6 Telco Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server AUS (v. 6.6) - noarch, x86_64 Red Hat Enterprise Linux Server Optional AUS (v. 6.6) - x86_64 Red Hat Enterprise Linux Server Optional TUS (v. 6.6) - x86_64 Red Hat Enterprise Linux Server TUS (v. 6.6) - noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646 and Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901. 4.
