Google Chrome < 43.0.2357.65 Multiple Vulnerabilities

High

Synopsis

The remote host contains a web browser that is vulnerable to multiple attack vectors.

Description

The version of Google Chrome on the remote host is prior to 43.0.2357.65 and is affected by the following vulnerabilities :

- A use-after-free memory error exists in the SpeechRecognitionClient implementation that allows remote attackers, using a crafted document, to execute arbitrary code. (CVE-2015-1251)

- The Write() and DoWrite() methods of the class PartialCircularBuffer do not properly handle wraps. A remote attacker, by using write operations with a large amount of data, can exploit this to bypass the sandbox protection or cause a denial of service. (CVE-2015-1252)

- The DOM implementation in Blink does not properly handle SCRIPT elements during adjustment of DOM node locations. A remote attacker, using crafted JavaScript code that appends a child to a SCRIPT element, can exploit this flaw to bypass the same origin policy. (CVE-2015-1253)

- The 'core/dom/Document.cpp' in Blink enables the inheritance of the 'designMode' attribute. A remote attacker, using a crafted web page, can utilize this to bypass the same origin policy via the availability of editing. (CVE-2015-1254)

- A use-after-free memory error exists in the WebAudio implementation when handling the stop action for an audio track. A remote attacker can exploit this to cause a denial of service or possibly execute arbitrary code. (CVE-2015-1255)

- A use-after-free memory error exists in the SVG implementation in Blink, related to the improper handling of a shadow tree for a use element. A remote attacker, using a crafted document, can exploit this to cause a denial of service or possibly execute arbitrary code. (CVE-2015-1256)

- The SVG implementation in Blink does not properly handle an insufficient number of values in an 'feColorMatrix' filter. A remote attacker, using a crafted document, can exploit this to cause a denial of service via a container overflow. (CVE-2015-1257)

- The libvpx library code was not compiled with an appropriate '--size-limit' value. This allows a remote attacker, using a crafted frame size in VP9 video data, to trigger a negative value for a size field, thus causing a denial of service or possibly having other impact. (CVE-2015-1258)

- Google PDFium does not properly initialize memory. A remote attacker can exploit this to cause a denial of service or possibly have other unspecified impact. (CVE-2015-1259)

- Multiple use-after-free memory errors exist the WebRTC implementation. A remote attacker can exploit these, by using a crafted JavaScript code that executes upon completion of a 'getUserMedia' request, to cause a denial of service or possibly have other unspecified impacts. (CVE-2015-1260)

- The file 'HarfBuzzShaper.cpp' in Blink does not properly initialize a certain width field. A remote attacker, using crafted Unicode text, can exploit this to cause a denial of service or have other unspecified impacts. (CVE-2015-1262)

- The Spellcheck API implementation does not use an HTTPS session for downloading a Hunspell dictionary. A man-in-the-middle attacker, using a crafted file, can exploit this flaw to deliver incorrect spelling suggestions or possibly have other unspecified impacts. (CVE-2015-1263)

- A cross-site scripting (XSS) vulnerability exists that is related to the Bookmarks feature. A remote attacker, using crafted data, can exploit this to inject arbitrary web script or HTML. (CVE-2015-1264)

- Multiple unspecified vulnerabilities exist that allow an attacker to cause a denial of service or possibly have other impact via unknown vectors. (CVE-2015-1265)

Solution

Upgrade to Google Chrome 43.0.2357.65 or later.
