| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2012-11-24 | CVE-2012-4538 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. | 4.9 |
| 2012-11-24 | CVE-2012-3433 | Resource Management Errors vulnerability in XEN 4.0.0/4.1.0 Xen 4.0 and 4.1 allows local HVM guest OS kernels to cause a denial of service (domain 0 VCPU hang and kernel panic) by modifying the physical address space in a way that triggers excessive shared page search time during the p2m teardown. | 4.9 |
| 2012-11-23 | CVE-2012-6036 | Permissions, Privileges, and Access Controls vulnerability in XEN 4.0.0/4.1.0/4.2.0 The (1) memc_save_get_next_page, (2) tmemc_restore_put_page and (3) tmemc_restore_flush_page functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 do not check for negative id pools, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or possibly execute arbitrary code via unspecified vectors. | 4.4 |
| 2012-11-23 | CVE-2012-6035 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 The do_tmem_destroy_pool function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly validate pool ids, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or execute arbitrary code via unspecified vectors. | 6.9 |
| 2012-11-23 | CVE-2012-6034 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 The (1) tmemc_save_get_next_page and (2) tmemc_save_get_next_inv functions and the (3) TMEMC_SAVE_GET_POOL_UUID sub-operation in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 "do not check incoming guest output buffer pointers," which allows local guest OS users to cause a denial of service (memory corruption and host crash) or execute arbitrary code via unspecified vectors. | 4.4 |
| 2012-11-23 | CVE-2012-6033 | Permissions, Privileges, and Access Controls vulnerability in XEN 4.0.0/4.1.0/4.2.0 The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations via unspecified vectors. | 4.4 |
| 2012-11-23 | CVE-2012-6032 | Numeric Errors vulnerability in XEN 4.0.0/4.1.0/4.2.0 Multiple integer overflows in the (1) tmh_copy_from_client and (2) tmh_copy_to_client functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (memory corruption and host crash) via unspecified vectors. | 4.9 |
| 2012-11-23 | CVE-2012-6031 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 The do_tmem_get function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (CPU hang and host crash) via unspecified vectors related to a spinlock being held in the "bad_copy error path." NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | 4.7 |
| 2012-11-23 | CVE-2012-6030 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 The do_tmem_op function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (host crash) and possibly have other unspecified impacts via unspecified vectors related to "broken locking checks" in an "error path." NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | 7.2 |
| 2012-11-23 | CVE-2012-3497 | Improper Input Validation vulnerability in XEN 4.0.0/4.1.0/4.2.0 (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2) TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS and (4) TMEMC_SAVE_END in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (NULL pointer dereference or memory corruption and host crash) or possibly have other unspecified impacts via a NULL client id. | 6.9 |
