Security update for xen SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2019:14001-1 Final 1 1 2019-04-01T09:26:17Z current 2019-04-01T09:26:17Z 2019-04-01T09:26:17Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for xen This update for xen fixes the following issues: Security issues fixed: - Fixed multiple access violations introduced by XENMEM_exchange hypercall which could allow a single PV guest to leak arbitrary amounts of memory, leading to a denial of service (bsc#1126192). - Fixed an issue which could allow a malicious unprivileged guest userspace process to escalate its privilege to that of other userspace processes in the same guest and potentially thereby to that of the guest operating system (bsc#1126201). - Fixed an issue which could allow an untrusted PV domain with access to a physical device to DMA into its own pagetables leading to privilege escalation (bsc#1126195). - Fixed an issue which could allow a malicious or buggy x86 PV guest kernels can mount a Denial of Service attack affecting the whole system (bsc#1126196). - CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp (bsc#1123157). - Fixed an issue which could allow malicious PV guests may cause a host crash or gain access to data pertaining to other guests.Additionally, vulnerable configurations are likely to be unstable even in the absence of an attack (bsc#1126198). - Fixed an issue which could allow malicious 64bit PV guests to cause a host crash (bsc#1127400). - Fixed an issue which could allow malicious or buggy guests with passed through PCI devices to be able to escalate their privileges, crash the host, or access data belonging to other guests. Additionally memory leaks were also possible (bsc#1126140). - Fixed a race condition issue which could allow malicious PV guests to escalate their privilege to that of the hypervisor (bsc#1126141). - CVE-2019-9824: Fixed an information leak in SLiRP networking implementation which could allow a user/process to read uninitialised stack memory contents (bsc#1129623). Other issues fixed: - Fixed an issue where VMs crashing when migrating between dom0 hosts (bsc#1031382). - Upstream bug fixes (bsc#1027519) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0). sdksp4-xen-14001,slessp4-xen-14001 Copyright SUSE LLC under the Creative Commons License 4.0 with Attribution (CC-BY-4.0) https://www.suse.com/support/update/announcement/2019/suse-su-201914001-1/ Link for SUSE-SU-2019:14001-1 https://lists.suse.com/pipermail/sle-security-updates/2019-April/005274.html E-Mail link for SUSE-SU-2019:14001-1 https://www.suse.com/support/security/rating/ SUSE Security Ratings https://bugzilla.suse.com/1027519 SUSE Bug 1027519 https://bugzilla.suse.com/1031382 SUSE Bug 1031382 https://bugzilla.suse.com/1123157 SUSE Bug 1123157 https://bugzilla.suse.com/1126140 SUSE Bug 1126140 https://bugzilla.suse.com/1126141 SUSE Bug 1126141 https://bugzilla.suse.com/1126192 SUSE Bug 1126192 https://bugzilla.suse.com/1126195 SUSE Bug 1126195 https://bugzilla.suse.com/1126196 SUSE Bug 1126196 https://bugzilla.suse.com/1126198 SUSE Bug 1126198 https://bugzilla.suse.com/1126201 SUSE Bug 1126201 https://bugzilla.suse.com/1127400 SUSE Bug 1127400 https://bugzilla.suse.com/1129623 SUSE Bug 1129623 https://www.suse.com/security/cve/CVE-2019-6778/ SUSE CVE CVE-2019-6778 page https://www.suse.com/security/cve/CVE-2019-9824/ SUSE CVE CVE-2019-9824 page SUSE Linux Enterprise Server 11 SP4 SUSE Linux Enterprise Server for SAP Applications 11 SP4 SUSE Linux Enterprise Software Development Kit 11 SP4 xen-devel-4.4.4_40-61.43.2 xen-4.4.4_40-61.43.2 xen-doc-html-4.4.4_40-61.43.2 xen-kmp-default-4.4.4_40_3.0.101_108.87-61.43.2 xen-kmp-pae-4.4.4_40_3.0.101_108.87-61.43.2 xen-libs-4.4.4_40-61.43.2 xen-libs-32bit-4.4.4_40-61.43.2 xen-tools-4.4.4_40-61.43.2 xen-tools-domU-4.4.4_40-61.43.2 xen-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-doc-html-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-kmp-default-4.4.4_40_3.0.101_108.87-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-kmp-pae-4.4.4_40_3.0.101_108.87-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-libs-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-libs-32bit-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-tools-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-tools-domU-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server 11 SP4 xen-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-doc-html-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-kmp-default-4.4.4_40_3.0.101_108.87-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-kmp-pae-4.4.4_40_3.0.101_108.87-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-libs-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-libs-32bit-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-tools-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-tools-domU-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 xen-devel-4.4.4_40-61.43.2 as a component of SUSE Linux Enterprise Software Development Kit 11 SP4 In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.
