Mageia 6: 2019-0179 Critical: VirtualBox MDS Attack Mitigation

This update provies Virtualbox 6.0.8 that fixes the Microarchitectural Data Sampling (MDS, also called ZombieLoad attack) vulnerabilities in Intel processors that can allow attackers to retrieve data being processed inside a CPU. . MGASA-2019-0179 - Updated virtualbox packages fix security vulnerabilities Publication date: 18 May 2019 URL: https://advisories.mageia.org/MGASA-2019-0179.html Type: security Affected Mageia releases: 6 CVE: CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091 This update provies Virtualbox 6.0.8 that fixes the Microarchitectural Data Sampling (MDS, also called ZombieLoad attack) vulnerabilities in Intel processors that can allow attackers to retrieve data being processed inside a CPU. The fixed / mitigated issues are: Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer. (CVE-2018-12126) Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results are stored in the 'load port' table until overwritten by newer operations. Certain load-port operations triggered by an attacker can be used to reveal data about previous stale requests leaking data back to the attacker via a timing side-channel. (CVE-2018-12127) A flaw was found in the implementation of the "fill buffer", amechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer while the data is fetched from higher level caches. This response time can be measured to infer data in the fill buffer. (CVE-2018-12130) Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11091) For other fixes in this update, see the referenced changelog.

Debian 8: DLA-1787-1 Critical: linux-4.9 Intel Data Exposure

Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to . Package : linux-4.9 Version : 4.9.168-1+deb9u2~deb8u1 CVE ID : CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Debian Bug : 928125 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. An updated intel-microcode package (only available in Debian non-free) will be provided via a separate DLA. The updated CPU microcode may also be available as part of a system firmware ("BIOS") update. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver, which was introduced by the update to 4.9.168 in the last security update. For Debian 8 "Jessie", these problems have been fixed in version 4.9.168-1+deb9u2~deb8u1. We recommend that you upgrade your linux-4.9 packages.

For more information on this set of vulnerabilities, check out https://support.scc.suse.com/s/kb?language=en_US Other fixes: - Added code to change LIBXL_HOTPLUG_TIMEOUT at runtime. The included README has details about the impact of this change (bsc#1120095) - Fixes in Live migrating PV domUs An earlier change broke live migration of PV domUs without a device model. The migration would stall for 10 seconds while the domU was paused, which caused network connections to drop. Fix this bytracking the need for a device model within libxl. (bsc#1079730, bsc#1098403, bsc#1111025) - Libvirt segfault when crash triggered on top of HVM guest (bsc#1120067) Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
