Updated chromium-browser-stable packages fix security vulnerabilities

Chromium-browser 43.0.2357.65 fixes a number of security issues: Use-after-free vulnerability in the SpeechRecognitionClient implementation in the Speech subsystem in Google Chrome before 43.0.2357.65 allows remote attackers to execute arbitrary code via a crafted document. (CVE-2015-1251) common/partial_circular_buffer.cc in Google Chrome before 43.0.2357.65 does not properly handle wraps, which allows remote attackers to bypass a sandbox protection mechanism or cause a denial of service (out-of-bounds write) via vectors that trigger a write operation with a large amount of data, related to the PartialCircularBuffer::Write and PartialCircularBuffer::DoWrite functions. (CVE-2015-1252) core/html/parser/HTMLConstructionSite.cpp in the DOM implementation in Blink, as used in Google Chrome before 43.0.2357.65, allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code that appends a child to a SCRIPT element, related to the insert and executeReparentTask functions. (CVE-2015-1253) core/dom/Document.cpp in Blink, as used in Google Chrome before 43.0.2357.65, enables the inheritance of the designMode attribute, which allows remote attackers to bypass the Same Origin Policy by leveraging the availability of editing. (CVE-2015-1254) Use-after-free vulnerability in content/renderer/media/webaudio_capturer_source.cc in the WebAudio implementation in Google Chrome before 43.0.2357.65 allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by leveraging improper handling of a stop action for an audio track. (CVE-2015-1255) Use-after-free vulnerability in the SVG implementation in Blink, as used in Google Chrome before 43.0.2357.65, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted document that leverages improper handling of a shadow tree for a use element. (CVE-2015-1256) platform/graphics/filters/FEColorMatrix.cpp in the SVG implementation in Blink, as used in Google Chrome before 43.0.2357.65, does not properly handle an insufficient number of values in an feColorMatrix filter, which allows remote attackers to cause a denial of service (container overflow) or possibly have unspecified other impact via a crafted document. (CVE-2015-1257) Google Chrome before 43.0.2357.65 relies on libvpx code that was not built with an appropriate --size-limit value, which allows remote attackers to trigger a negative value for a size field, and consequently cause a denial of service or possibly have unspecified other impact, via a crafted frame size in VP9 video data. (CVE-2015-1258) PDFium, as used in Google Chrome before 43.0.2357.65, does not properly initialize memory, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors. (CVE-2015-1259) Multiple use-after-free vulnerabilities in content/renderer/media/user_media_client_impl.cc in the WebRTC implementation in Google Chrome before 43.0.2357.65 allow remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that executes upon completion of a getUserMedia request. (CVE-2015-1260) platform/fonts/shaping/HarfBuzzShaper.cpp in Blink, as used in Google Chrome before 43.0.2357.65, does not initialize a certain width field, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted Unicode text. (CVE-2015-1262) The Spellcheck API implementation in Google Chrome before 43.0.2357.65 does not use an HTTPS session for downloading a Hunspell dictionary, which allows man-in-the-middle attackers to deliver incorrect spelling suggestions or possibly have unspecified other impact via a crafted file. (CVE-2015-1263) Cross-site scripting (XSS) vulnerability in Google Chrome before 43.0.2357.65 allows user-assisted remote attackers to inject arbitrary web script or HTML via crafted data that is improperly handled by the Bookmarks feature. (CVE-2015-1264) Multiple unspecified vulnerabilities in Google Chrome before 43.0.2357.65 allow attackers to cause a denial of service or possibly have other impact via unknown vectors. (CVE-2015-1265) Multiple vulnerabilities in V8 have been fixed at the tip of the 4.3 branch (currently 4.3.61.21).
