DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2016-08-02 | CVE-2016-6258 | Improper Access Control vulnerability in multiple products 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. | 7.2 |
2016-06-13 | CVE-2016-5302 | Improper Access Control vulnerability in Citrix Xenserver 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. | 7.5 |
2016-05-11 | CVE-2016-3712 | Integer Overflow or Wraparound vulnerability in multiple products Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode. | 5.5 |
2016-05-11 | CVE-2016-3710 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue. | 7.2 |
2016-04-13 | CVE-2015-8555 | Information Exposure vulnerability in multiple products 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. | 5.0 |
2016-01-22 | CVE-2016-1571 | Code vulnerability in multiple products 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. | 4.7 |
2015-06-03 | CVE-2015-4106 | Incorrect Authorization vulnerability in multiple products 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. | 4.6 |
2014-07-22 | CVE-2014-4948 | Denial of Service and Information Disclosure vulnerability in Citrix Xenserver 6.2.0 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). | 6.4 |
2014-07-22 | CVE-2014-4947 | Buffer Errors vulnerability in Citrix Xenserver 6.2.0 Buffer overflow in the HVM graphics console support in Citrix XenServer 6.2 Service Pack 1 and earlier has unspecified impact and attack vectors. | 10.0 |
2012-12-13 | CVE-2012-5512 | Configuration vulnerability in Citrix Xenserver 4.1.0 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. | 3.2 |
