DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2015-10-01 | CVE-2015-7311 | Code vulnerability in XEN libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | 3.6 |
2015-08-12 | CVE-2015-5166 | Permissions, Privileges, and Access Controls vulnerability in multiple products Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. | 7.2 |
2015-07-16 | CVE-2015-3259 | Permissions, Privileges, and Access Controls vulnerability in XEN Stack-based buffer overflow in the xl command line utility in Xen 4.1.x through 4.5.x allows local guest administrators to gain privileges via a long configuration argument. | 6.8 |
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 |
2015-06-03 | 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 |
2015-03-18 | 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 |
2015-03-12 | CVE-2015-2151 | Permissions, Privileges, and Access Controls vulnerability in multiple products The x86 emulator in Xen 3.2.x through 4.5.x does not properly ignore segment overrides for instructions with register operands, which allows local guest users to obtain sensitive information, cause a denial of service (memory corruption), or possibly execute arbitrary code via unspecified vectors. | 7.2 |
2015-03-12 | CVE-2015-2045 | Information Exposure vulnerability in multiple products The HYPERVISOR_xen_version hypercall in Xen 3.2.x through 4.5.x does not properly initialize data structures, which allows local guest users to obtain sensitive information via unspecified vectors. | 2.1 |
