CVSS v3.1 |
| An issue was discovered in Linux Foundation xapi in Citrix XenServer through 7.0. An authenticated read-only administrator can corrupt the host database. |
| The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. |
| Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants. |
| 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 xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. |
| 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. |
| Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. |
| 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 pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. |
| 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. |
| 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. |
| 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. |
| Buffer overflow in the HVM graphics console support in Citrix XenServer 6.2 Service Pack 1 and earlier has unspecified impact and attack 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. |
| 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. |
| Unspecified vulnerability in Citrix XenServer 6.2 Service Pack 1 and earlier allows attackers to cause a denial of service and obtain sensitive information by modifying the guest virtual hard disk (VHD). |
| 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. |
| 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. |
