  1. Description:

The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

Security Fix(es):

  • A flaw was found in the implementation of the "fill buffer", a mechanism 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)

  • 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-2019-11091)

(CVE-2019-11091)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 ESM: linux-image-3.13.0-170-generic 3.13.0-170.220~12.04.2+signed1 linux-image-3.13.0-170-generic-lpae 3.13.0-170.220~12.04.2 linux-image-3.13.0-170-lowlatency 3.13.0-170.220~12.04.2+signed1 linux-image-generic-lpae-lts-trusty 3.13.0.170.158 linux-image-generic-lts-trusty 3.13.0.170.158

After a standard system update you need to reboot your computer to make all the necessary changes.

Please note that fully mitigating the Microarchitectural Data Sampling (MDS) issues (CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, and CVE-2019-11091) requires corresponding processor microcode/firmware updates or, in virtual environments, hypervisor updates. 8) - aarch64, noarch, ppc64le, s390x, x86_64

  1. Description:

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Bug Fix(es):

  • Need to remove radix-tree symbols from the whitelist (BZ#1696222)

  • Installation of kernel-modules-extra rpm conflicts with kmod weak-modules (BZ#1703395)

Description:\n\nThe libvirt library contains a C API for managing and interacting with the\nvirtualization capabilities of Linux and other operating systems. In\naddition, libvirt provides tools for remote management of virtualized\nsystems. \n\nSecurity Fix(es):\n\n* A flaw was found in the implementation of the \"fill buffer\", a mechanism\nused by modern CPUs when a cache-miss is made on L1 CPU cache. If an\nattacker can generate a load operation that would create a page fault, the\nexecution will continue speculatively with incorrect data from the fill\nbuffer while the data is fetched from higher level caches. This response\ntime can be measured to infer data in the fill buffer. (CVE-2018-12130)\n\n* Modern Intel microprocessors implement hardware-level micro-optimizations\nto improve the performance of writing data back to CPU caches. The write\noperation is split into STA (STore Address) and STD (STore Data)\nsub-operations. These sub-operations allow the processor to hand-off\naddress generation logic into these sub-operations for optimized writes. \nBoth of these sub-operations write to a shared distributed processor\nstructure called the \u0027processor store buffer\u0027. As a result, an unprivileged\nattacker could use this flaw to read private data resident within the CPU\u0027s\nprocessor store buffer. (CVE-2018-12126)\n\n* Microprocessors use a \u2018load port\u2019 subcomponent to perform load operations\nfrom memory or IO. During a load operation, the load port receives data\nfrom the memory or IO subsystem and then provides the data to the CPU\nregisters and operations in the CPU\u2019s pipelines. Stale load operations\nresults are stored in the \u0027load port\u0027 table until overwritten by newer\noperations. Certain load-port operations triggered by an attacker can be\nused to reveal data about previous stale requests leaking data back to the\nattacker via a timing side-channel. (CVE-2019-11091)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, acknowledgments, and other related information, refer to the CVE\npage(s) listed in the References section. \n\n4.
