Security update for Xen SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2015:0746-1 Final 1 1 2015-03-30T14:25:37Z current 2015-03-30T14:25:37Z 2015-03-30T14:25:37Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for Xen The Virtualization service XEN was updated to fix various bugs and security issues. The following security issues have been fixed: * CVE-2015-2756: XSA-126: Unmediated PCI command register access in qemu could have lead to denial of service attacks against the host, if PCI cards are passed through to guests. * XSA-125: Long latency MMIO mapping operations were not preemptible. * CVE-2015-2151: XSA-123: Instructions with register operands ignored eventual segment overrides encoded for them. Due to an insufficiently conditional assignment such a bogus segment override could have, however, corrupted a pointer used subsequently to store the result of the instruction. * CVE-2015-2045: XSA-122: The code handling certain sub-operations of the HYPERVISOR_xen_version hypercall failed to fully initialize all fields of structures subsequently copied back to guest memory. Due to this hypervisor stack contents were copied into the destination of the operation, thus becoming visible to the guest. * CVE-2015-2044: XSA-121: Emulation routines in the hypervisor dealing with certain system devices checked whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that hypervisor stack contents were copied into the destination of the operation, thus becoming visible to the guest. Also fixed: * Regular crashes of dom-0 on different servers due to races in MCE access were fixed. bsc#907755 Security Issues: * CVE-2015-2044 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2044> * CVE-2015-2045 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2045> * CVE-2015-2151 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2151> * CVE-2015-2756 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-2756> The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0). slessp2-xen-201503 Copyright SUSE LLC under the Creative Commons License 4.0 with Attribution (CC-BY-4.0) https://www.suse.com/support/update/announcement/2015/suse-su-20150746-1/ Link for SUSE-SU-2015:0746-1 https://lists.suse.com/pipermail/sle-security-updates/2015-April/001356.html E-Mail link for SUSE-SU-2015:0746-1 https://www.suse.com/support/security/rating/ SUSE Security Ratings https://bugzilla.suse.com/907755 SUSE Bug 907755 https://bugzilla.suse.com/918995 SUSE Bug 918995 https://bugzilla.suse.com/918998 SUSE Bug 918998 https://bugzilla.suse.com/919464 SUSE Bug 919464 https://bugzilla.suse.com/922705 SUSE Bug 922705 https://bugzilla.suse.com/922706 SUSE Bug 922706 https://www.suse.com/security/cve/CVE-2015-2044/ SUSE CVE CVE-2015-2044 page https://www.suse.com/security/cve/CVE-2015-2045/ SUSE CVE CVE-2015-2045 page https://www.suse.com/security/cve/CVE-2015-2151/ SUSE CVE CVE-2015-2151 page https://www.suse.com/security/cve/CVE-2015-2756/ SUSE CVE CVE-2015-2756 page SUSE Linux Enterprise Server 11 SP2-LTSS xen-4.1.6_08-0.9.1 xen-devel-4.1.6_08-0.9.1 xen-doc-html-4.1.6_08-0.9.1 xen-doc-pdf-4.1.6_08-0.9.1 xen-kmp-default-4.1.6_08_3.0.101_0.7.29-0.9.1 xen-kmp-pae-4.1.6_08_3.0.101_0.7.29-0.9.1 xen-kmp-trace-4.1.6_08_3.0.101_0.7.29-0.9.1 xen-libs-4.1.6_08-0.9.1 xen-libs-32bit-4.1.6_08-0.9.1 xen-tools-4.1.6_08-0.9.1 xen-tools-domU-4.1.6_08-0.9.1 xen-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-devel-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-doc-html-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-doc-pdf-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-kmp-default-4.1.6_08_3.0.101_0.7.29-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-kmp-pae-4.1.6_08_3.0.101_0.7.29-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-kmp-trace-4.1.6_08_3.0.101_0.7.29-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-libs-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-libs-32bit-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-tools-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS xen-tools-domU-4.1.6_08-0.9.1 as a component of SUSE Linux Enterprise Server 11 SP2-LTSS The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size.
