| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2015-06-15 | CVE-2015-4164 | Resource Management Errors vulnerability in XEN The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. | 4.9 |
| 2015-06-15 | CVE-2015-4163 | Local Denial of Service vulnerability in Xen GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version. | 4.9 |
| 2015-06-03 | CVE-2015-4105 | Resource Management Errors vulnerability in XEN Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. | 4.9 |
| 2015-06-03 | CVE-2015-4104 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. | 7.8 |
| 2015-06-03 | CVE-2015-4103 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields. | 4.9 |
| 2015-04-28 | CVE-2015-3340 | Information Exposure vulnerability in multiple products Xen 4.2.x through 4.5.x does not initialize certain fields, which allows certain remote service domains to obtain sensitive information from memory via a (1) XEN_DOMCTL_gettscinfo or (2) XEN_SYSCTL_getdomaininfolist request. | 2.9 |
| 2015-04-01 | CVE-2015-2756 | Permissions, Privileges, and Access Controls vulnerability in multiple products QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | 4.9 |
| 2015-04-01 | CVE-2015-2752 | Improper Input Validation vulnerability in multiple products The XEN_DOMCTL_memory_mapping hypercall in Xen 3.2.x through 4.5.x, when using a PCI passthrough device, is not preemptible, which allows local x86 HVM domain users to cause a denial of service (host CPU consumption) via a crafted request to the device model (qemu-dm). | 4.9 |
| 2015-04-01 | CVE-2015-2751 | Code vulnerability in multiple products Xen 4.3.x, 4.4.x, and 4.5.x, when using toolstack disaggregation, allows remote domains with partial management control to cause a denial of service (host lock) via unspecified domctl operations. | 7.1 |
| 2015-03-18 | CVE-2015-2152 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.5.x and earlier enables certain default backends when emulating a VGA device for an x86 HVM guest qemu even when the configuration disables them, which allows local guest users to obtain access to the VGA console by (1) setting the DISPLAY environment variable, when compiled with SDL support, or connecting to the VNC server on (2) ::1 or (3) 127.0.0.1, when not compiled with SDL support. | 1.9 |
