| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2012-12-13 | CVE-2012-5514 | Local Denial of Service vulnerability in Xen The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors. local xen | 4.7 |
| 2012-12-13 | CVE-2012-5510 | Local Denial of Service vulnerability in Xen Grant Table Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. local xen | 4.7 |
| 2012-12-03 | CVE-2012-3432 | Permissions, Privileges, and Access Controls vulnerability in XEN The handle_mmio function in arch/x86/hvm/io.c in the MMIO operations emulator for Xen 3.3 and 4.x, when running an HVM guest, does not properly reset certain state information between emulation cycles, which allows local guest OS users to cause a denial of service (guest OS crash) via unspecified operations on MMIO regions. | 1.9 |
| 2012-11-23 | CVE-2012-3495 | Improper Input Validation vulnerability in multiple products 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. | 6.1 |
| 2012-11-21 | CVE-2012-4539 | Resource Management Errors vulnerability in XEN Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka "Grant table hypercall infinite loop DoS vulnerability." | 2.1 |
| 2012-11-21 | CVE-2012-4537 | Configuration vulnerability in XEN Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability." | 2.1 |
| 2012-11-21 | CVE-2012-4535 | Resource Management Errors vulnerability in XEN Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an "inappropriate deadline." | 1.9 |
| 2012-10-31 | CVE-2012-4544 | Improper Input Validation vulnerability in XEN The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk. | 2.1 |
| 2012-10-31 | CVE-2012-2625 | Improper Input Validation vulnerability in XEN and Xen-Unstable The PyGrub boot loader in Xen unstable before changeset 25589:60f09d1ab1fe, 4.2.x, and 4.1.x allows local para-virtualized guest users to cause a denial of service (memory consumption) via a large (1) bzip2 or (2) lzma compressed kernel image. | 2.7 |
| 2012-06-12 | CVE-2012-0217 | Buffer Errors vulnerability in Freebsd The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. | 7.2 |
