CVSS v3.1 |
| Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. |
| Citrix XenMobile Server before 10.5.0.24 allows man-in-the-middle attackers to trigger HTTP 302 redirections via vectors involving the HTTP Host header and a cached page. NOTE: the vendor reports "our internal analysis of this issue concluded that this was not a valid vulnerability" because an exploitation scenario would involve a man-in-the-middle attack against a TLS session |
| The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. |
| The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. |
| The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. |
| Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. |
| Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability. |
| The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. |
| XML external entity (XXE) vulnerability in Citrix XenMobile Server 9.x and 10.x before 10.5 RP3 allows attackers to obtain sensitive information via unspecified vectors. |
| Citrix XenApp 6.x before 6.5 HRP07 and 7.x before 7.9 and Citrix XenDesktop before 7.9 might allow attackers to weaken an unspecified security mitigation via vectors related to memory permission. |
| The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. |
| 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. |
| 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. |
| 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. |
| Citrix Worx Home for iOS before 10.3.6 and XenMobile MDX Toolkit for iOS before 10.3.6 might allow physically proximate attackers to bypass in-application Apple Touch ID authentication via unspecified vectors, related to an application requiring re-authentication. |
| 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. |
| Cross-site scripting (XSS) vulnerability in the Web User Interface in Citrix XenMobile Server 10.0, 10.1 before Rolling Patch 4, and 10.3 before Rolling Patch 1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. |
| The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check. |
| Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors. |
| Citrix XenMobile MDX Toolkit before 9.0.4, when used to wrap iOS 8 applications, does not properly encrypt cached application data, which allows context-dependent attackers to obtain sensitive information by reading the cache. |
