CVE-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-07-01 | 4.6 MEDIUM | 7.5 HIGH |
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. | |||||
CVE-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-07-01 | 4.6 MEDIUM | 7.9 HIGH |
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. | |||||
CVE-2016-6258 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-07-01 | 7.2 HIGH | 8.8 HIGH |
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. | |||||
CVE-2015-8555 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-07-01 | 5.0 MEDIUM | 8.6 HIGH |
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. | |||||
CVE-2012-3495 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-07-01 | 6.1 MEDIUM | N/A |
The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors. | |||||
CVE-2016-10025 | 2 Citrix, Xen | 2 Xenserver, Xen | 2017-01-27 | 2.1 LOW | 5.5 MEDIUM |
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check. | |||||
CVE-2016-6259 | 2 Citrix, Xen | 2 Xenserver, Xen | 2016-08-04 | 4.9 MEDIUM | 6.2 MEDIUM |
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. | |||||
CVE-2016-5302 | 1 Citrix | 1 Xenserver | 2016-06-20 | 7.5 HIGH | 9.8 CRITICAL |
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. | |||||
CVE-2012-3516 | 2 Citrix, Xen | 2 Xenserver, Xen | 2013-02-01 | 6.9 MEDIUM | N/A |
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. | |||||
CVE-2010-2619 | 1 Citrix | 1 Xenserver | 2010-07-06 | 1.9 LOW | N/A |
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." | |||||
CVE-2010-0633 | 1 Citrix | 1 Xenserver | 2010-03-18 | 4.6 MEDIUM | N/A |
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. |
