The following security issues have been addressed : XSA-84: CVE-2014-1894: Xen 3.2 (and presumably earlier) exhibit both problems with the overflow issue being present for more than just the suboperations listed above. (bnc#860163) XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1, while not affected by the above overflow, have a different overflow issue on FLASK_{GET,SET}BOOL and expose unreasonably large memory allocation to arbitrary guests. (bnc#860163) XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER and FLASK_CONTEXT_TO_SID suboperations of the flask hypercall are vulnerable to an integer overflow on the input size. The hypercalls attempt to allocate a buffer which is 1 larger than this size and is therefore vulnerable to integer overflow and an attempt to allocate then access a zero byte buffer. (bnc#860163) XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue. (bnc#853049) XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. (bnc#849668) XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). (bnc#849667) XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. (bnc#848657) XSA-67: CVE-2013-4368: The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. (bnc#842511) XSA-66: CVE-2013-4361: The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction. (bnc#841766) XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. (bnc#840592) XSA-62: CVE-2013-1442: Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers. (bnc#839596) XSA-61: CVE-2013-4329: The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction. (bnc#839618) XSA-60: CVE-2013-2212: The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling chaches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. (bnc#831120) XSA-58: CVE-2013-1918: Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to last seen 2020-06-05 modified 2015-05-20 plugin id 83616 published 2015-05-20 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/83616 title SUSE SLES11 Security Update : Xen (SUSE-SU-2014:0446-1) NASL family SuSE Local Security Checks NASL id OPENSUSE-2013-310.NASL description XEN was updated to fix various bugs and security issues : Security issues fixed : -

Please review the CVE identifiers referenced below for details. Impact : Guest domains could possibly gain privileges, execute arbitrary code, or cause a Denial of Service on the host domain (Dom0). Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround : The CVEs listed below do not currently have fixes, but only apply to Xen setups which have “tmem” specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it.

Although these requests are denied by the I/OMMU, the hypervisor needs to handle the interrupt and clear the error from the I/OMMU, and this can be used to live-lock a CPU and potentially hang the host. - CVE-2012-4535 ( XSA 20): Timer overflow DoS vulnerability A guest which sets a VCPU with an inappropriate deadline can cause an infinite loop in Xen, blocking the affected physical CPU indefinitely. - CVE-2012-4537 ( XSA 22): Memory mapping failure DoS vulnerability When set_p2m_entry fails, Xen last seen 2020-03-17 modified 2012-12-09 plugin id 63188 published 2012-12-09 reporter This script is Copyright (C) 2012-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/63188 title Debian DSA-2582-1 : xen - several vulnerabilities NASL family SuSE Local Security Checks NASL id OPENSUSE-2012-870.NASL description This update of XEN fixes various denial of service bugs. - bnc#789945 - CVE-2012-5510: xen: Grant table version switch list corruption vulnerability (XSA-26) - bnc#789944 - CVE-2012-5511: xen: Several HVM operations do not validate the range of their inputs (XSA-27) - bnc#789940 - CVE-2012-5512: xen: HVMOP_get_mem_access crash / HVMOP_set_mem_access information leak (XSA-28) - bnc#789951 - CVE-2012-5513: xen: XENMEM_exchange may overwrite hypervisor memory (XSA-29) - bnc#789948 - CVE-2012-5514: xen: Missing unlock in guest_physmap_mark_populate_on_demand() (XSA-30) - bnc#789950 - CVE-2012-5515: xen: Several memory hypercall operations allow invalid extent order values (XSA-31) - bnc#789988 - FATAL PAGE FAULT in hypervisor (arch_do_domctl) 25931-x86-domctl-iomem-mapping-checks.patch - Upstream patches from Jan 26132-tmem-save-NULL-check.patch 26134-x86-shadow-invlpg-check.patch 26148-vcpu-timer-overflow.patch (Replaces CVE-2012-4535-xsa20.patch) 26149-x86-p2m-physmap-error-path.patch (Replaces CVE-2012-4537-xsa22.patch) 26150-x86-shadow-unhook-toplevel-check.patch (Replaces CVE-2012-4538-xsa23.patch) 26151-gnttab-compat-get-status-frames.patch (Replaces CVE-2012-4539-xsa24.patch) - bnc#777628 - guest last seen 2020-06-05 modified 2014-06-13 plugin id 74852 published 2014-06-13 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/74852 title openSUSE Security Update : xen (openSUSE-SU-2012:1685-1) NASL family SuSE Local Security Checks NASL id SUSE_11_XEN-130313.NASL description XEN has been updated to fix various bugs and security issues : - (XSA 36) To avoid an erratum in early hardware, the Xen AMD IOMMU code by default choose to use a single interrupt remapping table for the whole system.
