DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
2014-11-24 | CVE-2014-9030 | Improper Input Validation vulnerability in multiple products The do_mmu_update function in arch/x86/mm.c in Xen 3.2.x through 4.4.x does not properly manage page references, which allows remote domains to cause a denial of service by leveraging control over an HVM guest and a crafted MMU_MACHPHYS_UPDATE. | 7.1 |
2014-11-19 | CVE-2014-8595 | Code vulnerability in multiple products arch/x86/x86_emulate/x86_emulate.c in Xen 3.2.1 through 4.4.x does not properly check privileges, which allows local HVM guest users to gain privileges or cause a denial of service (crash) via a crafted (1) CALL, (2) JMP, (3) RETF, (4) LCALL, (5) LJMP, or (6) LRET far branch instruction. | 1.9 |
2014-10-02 | CVE-2014-7156 | Permissions, Privileges, and Access Controls vulnerability in XEN The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors. | 3.3 |
2014-10-02 | CVE-2014-7155 | Permissions, Privileges, and Access Controls vulnerability in multiple products The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service (guest crash) or gain guest kernel mode privileges via vectors involving an (1) HLT, (2) LGDT, (3) LIDT, or (4) LMSW instruction. | 5.8 |
2014-04-01 | CVE-2014-1893 | Numeric Errors vulnerability in XEN Multiple integer overflows in the (1) FLASK_GETBOOL and (2) FLASK_SETBOOL suboperations in the flask hypercall in Xen 4.1.x, 3.3.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1894. | 5.2 |
2014-04-01 | CVE-2014-1892 | Improper Restriction of Operations Within the Bounds of A Memory Buffer vulnerability in XEN Xen 3.3 through 4.1, when XSM is enabled, allows local users to cause a denial of service via vectors related to a "large memory allocation," a different vulnerability than CVE-2014-1891, CVE-2014-1893, and CVE-2014-1894. | 5.2 |
2014-04-01 | CVE-2014-1891 | Numeric Errors vulnerability in XEN Multiple integer overflows in the (1) FLASK_GETBOOL, (2) FLASK_SETBOOL, (3) FLASK_USER, and (4) FLASK_CONTEXT_TO_SID suboperations in the flask hypercall in Xen 4.3.x, 4.2.x, 4.1.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1892, CVE-2014-1893, and CVE-2014-1894. | 5.2 |
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 |
2013-12-24 | 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 |
