Blink, as used in Google Chrome before 43.0.2357.130, does not properly restrict the creation context during creation of a DOM wrapper, which allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code that uses a Blink public API, related to WebArrayBufferConverter.cpp, WebBlob.cpp, WebDOMError.cpp, and WebDOMFileSystem.cpp.

The version of Google Chrome OS on the remote mobile host is prior to 43.0.2357.125 and thus unpatched for the following vulnerabilities :

 - A scheme validation error exists in WebUI. A remote attacker can exploit this to have an unspecified impact. (CVE-2015-1266) 
 - A cross-origin bypass vulnerability exists in Blink due to an unspecified flaw that is triggered when handling the creation context passed through public APIs. A remote attacker can exploit this to bypass the cross-origin policy. (CVE-2015-1267) 
 - A cross-origin bypass vulnerability exists in Blink due to an unspecified flaw in its V8 bindings. A remote attacker can exploit this to bypass the cross-origin policy. (CVE-2015-1268) 
 - A normalization bypass vulnerability exists in the HSTS/HPKP preload list. A remote attacker can exploit this to bypass HSTS/HPKP preloads and have a connection use HTTP instead of the expected HTTPS. (CVE-2015-1269)

The remote host is affected by the vulnerability described in GLSA-201507-18 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could bypass security restrictions.
  Workaround :

    There is no known workaround at this time.

Several vulnerabilities were discovered in the chromium web browser.

  - CVE-2015-1283     Huzaifa Sidhpurwala discovered a buffer overflow in the     expat library.

  - CVE-2015-1284     Atte Kettunen discovered that the maximum number of page     frames was not correctly checked.

  - CVE-2015-1285     gazheyes discovered an information leak in the XSS     auditor, which normally helps to prevent certain classes     of cross-site scripting problems.

  - CVE-2015-1286     A cross-site scripting issue was discovered in the     interface to the v8 JavaScript library.

  - CVE-2015-1287     filedescriptor discovered a way to bypass the Same     Origin Policy.

  - CVE-2015-1289     The chrome 44 development team found and fixed various     issues during internal auditing.

In addition to the above issues, Google disabled the hotword extension by default in this version, which if enabled downloads files without the user's intervention.

It was discovered that Chromium did not properly consider the scheme when determining whether a URL is associated with a WebUI SiteInstance. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass security restrictions. (CVE-2015-1266)

It was discovered that Blink did not properly restrict the creation context during creation of a DOM wrapper. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2015-1267, CVE-2015-1268)

It was discovered that Chromium did not properly canonicalize DNS hostnames before comparing to HSTS or HPKP preload entries. An attacker could potentially exploit this to bypass intended access restrictions. (CVE-2015-1269).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated chromium-browser packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Chromium is an open source web browser, powered by WebKit (Blink).

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash or, potentially, execute arbitrary code with the privileges of the user running Chromium. (CVE-2015-1266, CVE-2015-1267, CVE-2015-1268, CVE-2015-1269)

All Chromium users should upgrade to these updated packages, which contain Chromium version 43.0.2357.130, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

chromium was updated to 43.0.2357.130 to fix several security issues and bugs.

The following vulnerabilities were fixed :

  - CVE-2015-1266: Scheme validation error in WebUI

  - CVE-2015-1268: Cross-origin bypass in Blink

  - CVE-2015-1267: Cross-origin bypass in Blink

  - CVE-2015-1269: Normalization error in HSTS/HPKP preload     list

  - boo#935022: Prevent Chromium from downloading a binary     blob for speech recognition

Contains the following non-security changes :

  - resolved browser font magnification/scaling issue.

  - Fixed an issue where sometimes a blank page would print

  - Icons not displaying properly on Linux

The version of Google Chrome installed on the remote Mac OS X host is prior to 43.0.2357.130. It is, therefore, affected by multiple vulnerabilities :

  - A scheme validation error exists in WebUI. A remote     attacker can exploit this to have an unspecified impact.
    (CVE-2015-1266)

  - A cross-origin bypass vulnerability exists in Blink due     to an unspecified flaw that is triggered when handling     the creation context passed through public APIs. A     remote attacker can exploit this to bypass the     cross-origin policy. (CVE-2015-1267)

  - A cross-origin bypass vulnerability exists in Blink due     to an unspecified flaw in its V8 bindings. A remote     attacker can exploit this to bypass the cross-origin     policy. (CVE-2015-1268)

  - A normalization bypass vulnerability exists in the     HSTS/HPKP preload list. A remote attacker can exploit     this to bypass HSTS/HPKP preloads and have a connection     use HTTP instead of the expected HTTPS. (CVE-2015-1269)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Google Chrome installed on the remote Windows host is prior to 43.0.2357.130. It is, therefore, affected by multiple vulnerabilities :

  - A scheme validation error exists in WebUI. A remote     attacker can exploit this to have an unspecified impact.
    (CVE-2015-1266)

  - A cross-origin bypass vulnerability exists in Blink due     to an unspecified flaw that is triggered when handling     the creation context passed through public APIs. A     remote attacker can exploit this to bypass the     cross-origin policy. (CVE-2015-1267)

  - A cross-origin bypass vulnerability exists in Blink due     to an unspecified flaw in its V8 bindings. A remote     attacker can exploit this to bypass the cross-origin     policy. (CVE-2015-1268)

  - A normalization bypass vulnerability exists in the     HSTS/HPKP preload list. A remote attacker can exploit     this to bypass HSTS/HPKP preloads and have a connection     use HTTP instead of the expected HTTPS. (CVE-2015-1269)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
