| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2013-12-24 | CVE-2013-4553 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). | 5.2 |
| 2013-12-13 | CVE-2013-6400 | Permissions, Privileges, and Access Controls vulnerability in XEN Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors. | 6.8 |
| 2013-11-23 | CVE-2013-6375 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.2.x and 4.3.x, when using Intel VT-d for PCI passthrough, does not properly flush the TLB after clearing a present translation table entry, which allows local guest administrators to cause a denial of service or gain privileges via unspecified vectors related to an "inverted boolean parameter." | 7.9 |
| 2013-11-18 | CVE-2013-4551 | Improper Input Validation vulnerability in XEN Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution." | 5.7 |
| 2013-11-02 | CVE-2013-4416 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN The Ocaml xenstored implementation (oxenstored) in Xen 4.1.x, 4.2.x, and 4.3.x allows local guest domains to cause a denial of service (domain shutdown) via a large message reply. | 5.2 |
| 2013-11-02 | CVE-2013-4494 | Improper Input Validation vulnerability in multiple products Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. | 5.2 |
| 2013-10-17 | CVE-2013-4371 | Resource Management Errors vulnerability in XEN Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors. | 4.4 |
| 2013-10-17 | CVE-2013-4370 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN The ocaml binding for the xc_vcpu_getaffinity function in Xen 4.2.x and 4.3.x frees certain memory that may still be intended for use, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors that trigger a (1) use-after-free or (2) double free. | 4.6 |
| 2013-10-17 | CVE-2013-4369 | NULL pointer Dereference Remote Denial of Service vulnerability in Xen The xlu_vif_parse_rate function in the libxlu library in Xen 4.2.x and 4.3.x allows local users to cause a denial of service (NULL pointer dereference) by using the "@" character as the VIF rate configuration. local xen | 1.9 |
