| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2014-01-07 | CVE-2011-1166 | Improper Input Validation vulnerability in XEN Xen, possibly before 4.0.2, allows local 64-bit PV guests to cause a denial of service (host crash) by specifying user mode execution without user-mode pagetables. | 5.5 |
| 2013-12-27 | CVE-2011-2519 | Null Pointer Dereference vulnerability in multiple products Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction. | 5.5 |
| 2013-12-24 | CVE-2013-4554 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. | 5.2 |
| 2013-10-17 | CVE-2013-4368 | Information Exposure vulnerability in XEN The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. | 1.9 |
| 2013-08-23 | CVE-2013-2196 | Remote Privilege Escalation vulnerability in Xen Multiple unspecified vulnerabilities in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "other problems" that are not CVE-2013-2194 or CVE-2013-2195. local xen | 6.9 |
| 2013-08-23 | CVE-2013-2195 | Numeric Errors vulnerability in XEN The Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "pointer dereferences" involving unexpected calculations. | 6.9 |
| 2013-08-23 | CVE-2013-2194 | Numeric Errors vulnerability in XEN Multiple integer overflows in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel. | 6.9 |
| 2013-05-13 | CVE-2013-1917 | Improper Input Validation vulnerability in XEN Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not clear the NT flag when using an IRET after a SYSENTER instruction, which allows PV guest users to cause a denial of service (hypervisor crash) by triggering a #GP fault, which is not properly handled by another IRET instruction. | 1.9 |
| 2013-04-12 | CVE-2013-1920 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running "under memory pressure" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors. | 4.4 |
| 2013-02-13 | CVE-2013-0231 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in multiple products The pciback_enable_msi function in the PCI backend driver (drivers/xen/pciback/conf_space_capability_msi.c) in Xen for the Linux kernel 2.6.18 and 3.8 allows guest OS users with PCI device access to cause a denial of service via a large number of kernel log messages. | 4.9 |
