v8: numeric casting issues

Google V8, as used in Google Chrome before 34.0.1847.116, does not properly use numeric casts during handling of typed arrays, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JavaScript code.

Integer overflow in the SoftwareFrameManager::SwapToNewFrame function in content/browser/renderer_host/software_frame_manager.cc in the software compositor in Google Chrome before 34.0.1847.116 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger an attempted mapping of a large amount of renderer memory.

v8: memory corruption issue fixed in Google Chrome 34.0.1847.116

Google V8, as used in Google Chrome before 34.0.1847.116, does not properly implement lazy deoptimization, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted JavaScript code, as demonstrated by improper handling of a heap allocation of a number outside the Small Integer (aka smi) range.

Multiple integer overflows in the replace-data functionality in the CharacterData interface implementation in core/dom/CharacterData.cpp in Blink, as used in Google Chrome before 34.0.1847.137, allow remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to ranges.

Integer overflow in the AudioInputRendererHost::OnCreateStream function in content/browser/renderer_host/media/audio_input_renderer_host.cc in Google Chrome before 35.0.1916.114 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger a large shared-memory allocation.

xen: integer overflow in several XSM/Flask hypercalls (xsa-84)

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.

xen: integer overflow in several XSM/Flask hypercalls (xsa-84)

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.

xen: integer overflow in several XSM/Flask hypercalls (xsa-84)

Multiple integer overflows in unspecified suboperations in the flask hypercall in Xen 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-2014-1893.

xen: Off-by-one error in FLASK_AVC_CACHESTAT hypercall (xsa-85)

Off-by-one error in the flask_security_avc_cachestats function in xsm/flask/flask_op.c in Xen 4.2.x and 4.3.x, when the maximum number of physical CPUs are in use, allows local users to cause a denial of service (host crash) or obtain sensitive information from hypervisor memory by leveraging a FLASK_AVC_CACHESTAT hypercall, which triggers a buffer over-read.

Integer signedness error in system/core/adb/adb_client.c in Android Debug Bridge (ADB) for Android 4.4 in the Android SDK Platform Tools 18.0.1 allows ADB servers to execute arbitrary code via a negative length value, which bypasses a signed comparison and triggers a stack-based buffer overflow.

postgresql: multiple integer overflows in hstore_io.c

Multiple integer overflows in contrib/hstore/hstore_io.c in PostgreSQL 9.0.x before 9.0.16, 9.1.x before 9.1.12, 9.2.x before 9.2.7, and 9.3.x before 9.3.3 allow remote authenticated users to have unspecified impact via vectors related to the (1) hstore_recv, (2) hstore_from_arrays, and (3) hstore_from_array functions in contrib/hstore/hstore_io.c; and the (4) hstoreArrayToPairs function in contrib/hstore/hstore_op.c, which triggers a buffer overflow. NOTE: this issue was SPLIT from CVE-2014-0064 because it has a different set of affected versions.
