CVSS v3.1 |
| Citrix XenDesktop 7.x, 5.x, and 4.x, when pooled random desktop groups is enabled and ShutdownDesktopsAfterUse is disabled, allows local guest users to gain access to another user's desktop via unspecified vectors. |
| Citrix XenServer 7.0 before Hotfix XS70E003, when a deployment has been upgraded from an earlier release, might allow remote attackers on the management network to "compromise" a host by leveraging credentials for an Active Directory account. |
| Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. |
| QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors. |
| Citrix Studio before 7.6.1000, Citrix XenDesktop 7.x before 7.6 LTSR Cumulative Update 1 (CU1), and Citrix XenApp 7.5 and 7.6 allow attackers to set Access Policy rules on the XenDesktop Delivery Controller via unspecified vectors. |
| PHYSDEVOP_map_pirq in Xen 4.1 and 4.2 and Citrix XenServer 6.0.2 and earlier allows local HVM guest OS kernels to cause a denial of service (host crash) and possibly read hypervisor or guest memory via vectors related to a missing range check of map->index. |
| Unspecified vulnerability in Citrix XenMobile Device Manager server (formerly Zenprise Device Manager server) 8.5, 8.6, and MDM 8.0.1 allows remote attackers to obtain sensitive information via unknown vectors. |
| The vbd_create function in Xen 3.1.2, when the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 is used, allows guest OS users to cause a denial of service (host OS panic) via an attempted access to a virtual CD-ROM device through the blkback driver. NOTE: some of these details are obtained from third party information. |
| The NDVM in Citrix XenClient XT before 2.1.3 and 3.x before 3.1.4 allows remote attackers to execute arbitrary commands by using the UIVM to create a network connection. |
| The do_block_io_op function in (1) drivers/xen/blkback/blkback.c and (2) drivers/xen/blktap/blktap.c in Xen before 3.4.0 for the Linux kernel 2.6.18, and possibly other versions, allows guest OS users to cause a denial of service (infinite loop and CPU consumption) via a large production request index to the blkback or blktap back-end drivers. NOTE: some of these details are obtained from third party information. |
| Unspecified vulnerability in Citrix XenServer 5.0 Update 3 and earlier, and 5.5, allows local users to bypass authentication and execute unspecified Xen API (XAPI) calls via unknown vectors. |
| Citrix XenServer 5.0 Update 2 and earlier, and 5.5 Update 1 and earlier, when using a pvops kernel, allows guest users to cause a denial of service in the host via unspecified vectors that trigger "incorrectly set flags." |
| The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly, related to (1) netback, (2) blkback, or (3) blktap. |
| The GNTTABOP_swap_grant_ref sub-operation in the grant table hypercall in Xen 4.2 and Citrix XenServer 6.0.2 allows local guest kernels or administrators to cause a denial of service (host crash) and possibly gain privileges via a crafted grant reference that triggers a write to an arbitrary hypervisor memory location. |
| The set_debugreg hypercall in include/asm-x86/debugreg.h in Xen 4.0, 4.1, and 4.2, and Citrix XenServer 6.0.2 and earlier, when running on x86-64 systems, allows local OS guest users to cause a denial of service (host crash) by writing to the reserved bits of the DR7 debug control register. |
| Citrix XenDesktop Virtual Desktop Agent (VDA) 5.6.x before 5.6.200, when making changes to the server-side policy that control USB redirection, does not propagate changes to the VDA, which allows authenticated users to retain access to the USB device. |
| Array index error in the HVMOP_set_mem_access handler in Xen 4.1 allows local HVM guest OS administrators to cause a denial of service (crash) or obtain sensitive information via unspecified vectors. |
| tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allows local users to cause a denial of service (management software infinite loop and management domain resource consumption) via unspecified vectors related to "Lack of error checking in the decompression loop." |
| Citrix XenDesktop 7.0, when upgraded from XenDesktop 5.x, does not properly enforce policy rule permissions, which allows remote attackers to bypass intended restrictions. |
| Multiple integer overflows in tools/libxc/xc_dom_bzimageloader.c in Xen 3.2, 3.3, 4.0, and 4.1 allow local users to cause a denial of service and possibly execute arbitrary code via a crafted paravirtualised guest kernel image that triggers (1) a buffer overflow during a decompression loop or (2) an out-of-bounds read in the loader involving unspecified length fields. |
