CVE-2012-2934 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
Xen 4.0, and 4.1, when running a 64-bit PV guest on "older" AMD CPUs, does not properly protect against a certain AMD processor bug, which allows local guest OS users to cause a denial of service (host hang) via sequential execution of instructions across a non-canonical boundary, a different vulnerability than CVE-2012-0217. | |||||
CVE-2013-4494 | 2 Debian, Xen | 2 Debian Linux, Xen | 2025-04-11 | 5.2 MEDIUM | N/A |
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. | |||||
CVE-2011-1166 | 1 Xen | 1 Xen | 2025-04-11 | 5.5 MEDIUM | N/A |
Xen, possibly before 4.0.2, allows local 64-bit PV guests to cause a denial of service (host crash) by specifying user mode execution without user-mode pagetables. | |||||
CVE-2014-1950 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors. | |||||
CVE-2012-4411 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
The graphical console in Xen 4.0, 4.1 and 4.2 allows local OS guest administrators to obtain sensitive host resource information via the qemu monitor. NOTE: this might be a duplicate of CVE-2007-0998. | |||||
CVE-2013-1920 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | N/A |
Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors. | |||||
CVE-2013-1964 | 1 Xen | 1 Xen | 2025-04-11 | 6.9 MEDIUM | N/A |
Xen 4.0.x and 4.1.x incorrectly releases a grant reference when releasing a non-v1, non-transitive grant, which allows local guest administrators to cause a denial of service (host crash), obtain sensitive information, or possibly have other impacts via unspecified vectors. | |||||
CVE-2012-6033 | 1 Xen | 1 Xen | 2025-04-11 | 4.4 MEDIUM | N/A |
The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | |||||
CVE-2012-3433 | 1 Xen | 1 Xen | 2025-04-11 | 4.9 MEDIUM | N/A |
Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown. | |||||
CVE-2013-2076 | 1 Xen | 1 Xen | 2025-04-11 | 4.3 MEDIUM | N/A |
Xen 4.0.x, 4.1.x, and 4.2.x, when running on AMD64 processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one domain to determine portions of the state of floating point instructions of other domains, which can be leveraged to obtain sensitive information such as cryptographic keys, a similar vulnerability to CVE-2006-1056. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels. | |||||
CVE-2012-3432 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions. | |||||
CVE-2012-0218 | 1 Xen | 1 Xen | 2025-04-11 | 1.9 LOW | N/A |
Xen 3.4, 4.0, and 4.1, when the guest OS has not registered a handler for a syscall or sysenter instruction, does not properly clear a flag for exception injection when injecting a General Protection Fault, which allows local PV guest OS users to cause a denial of service (guest crash) by later triggering an exception that would normally be handled within Xen. | |||||
CVE-2013-4356 | 1 Xen | 1 Xen | 2025-04-11 | 5.4 MEDIUM | N/A |
Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). | |||||
CVE-2013-0151 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
The do_hvm_op function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x86_32 platform does not prevent HVM_PARAM_NESTEDHVM (aka nested virtualization) operations, which allows guest OS users to cause a denial of service (long-duration page mappings and host OS crash) by leveraging administrative access to an HVM guest in a domain with a large number of VCPUs. | |||||
CVE-2013-2211 | 1 Xen | 1 Xen | 2025-04-11 | 7.4 HIGH | N/A |
The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors. | |||||
CVE-2012-0217 | 8 Citrix, Freebsd, Illumos and 5 more | 11 Xenserver, Freebsd, Illumos and 8 more | 2025-04-11 | 7.2 HIGH | N/A |
The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier. | |||||
CVE-2012-6030 | 1 Xen | 1 Xen | 2025-04-11 | 7.2 HIGH | N/A |
The do_tmem_op function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (host crash) and possibly have other unspecified impacts via unspecified vectors related to "broken locking checks" in an "error path." NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | |||||
CVE-2011-2519 | 2 Redhat, Xen | 4 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Workstation and 1 more | 2025-04-11 | 5.5 MEDIUM | N/A |
Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction. | |||||
CVE-2012-5513 | 1 Xen | 1 Xen | 2025-04-11 | 6.9 MEDIUM | N/A |
The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. | |||||
CVE-2013-4416 | 1 Xen | 1 Xen | 2025-04-11 | 5.2 MEDIUM | N/A |
The Ocaml xenstored implementation (oxenstored) in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service (domain shutdown) via a large message reply. |
