Updated chromium-browser packages that fix two 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).

Two flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to bypass cross origin restrictions, and access or modify data from an unrelated website. (CVE-2015-1303, CVE-2015-1304)

All Chromium users should upgrade to these updated packages, which contain Chromium version 45.0.2454.101, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

Google Chrome Releases reports :

Two vulnerabilities were fixed in this release :

- [530301] High CVE-2015-1303: Cross-origin bypass in DOM. Credit to Mariusz Mlynski.

- [531891] High CVE-2015-1304: Cross-origin bypass in V8. Credit to Mariusz Mlynski.

Several vulnerabilities have been discovered in the chromium web browser.

  - CVE-2015-1303     Mariusz Mlynski discovered a way to bypass the Same     Origin Policy in the DOM implementation.

  - CVE-2015-1304     Mariusz Mlynski discovered a way to bypass the Same     Origin Policy in the v8 JavaScript library.

  - CVE-2015-6755     Mariusz Mlynski discovered a way to bypass the Same     Origin Policy in blink/webkit.

  - CVE-2015-6756     A use-after-free issue was found in the pdfium library.

  - CVE-2015-6757     Collin Payne found a use-after-free issue in the     ServiceWorker implementation.

  - CVE-2015-6758     Atte Kettunen found an issue in the pdfium library.

  - CVE-2015-6759     Muneaki Nishimura discovered an information leak.

  - CVE-2015-6760     Ronald Crane discovered a logic error in the ANGLE     library involving lost device events.

  - CVE-2015-6761     Aki Helin and Khalil Zhani discovered a memory     corruption issue in the ffmpeg library.

  - CVE-2015-6762     Muneaki Nishimura discovered a way to bypass the Same     Origin Policy in the CSS implementation.

  - CVE-2015-6763     The chrome 46 development team found and fixed various     issues during internal auditing. Also multiple issues     were fixed in the v8 JavaScript library, version     4.6.85.23.

The version of Google Chrome installed on the remote Windows host is prior to 45.0.2454.101. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the DOM that allows a     remote attacker to bypass the cross-origin policy.
    (CVE-2015-1303)

  - A flaw exists in the V8 JavaScript engine when handling     Object.observe calls on access-checked objects. A remote     attacker may exploit this to bypass the cross-origin     policy. (CVE-2015-1304)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2757-1 advisory.

    Two security issues were discovered in Blink and V8. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to bypass same-origin restrictions.
    (CVE-2015-1303, CVE-2015-1304)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 Mac OS X host is prior to 45.0.2454.101. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the DOM that allows a     remote attacker to bypass the cross-origin policy.
    (CVE-2015-1303)

  - A flaw exists in the V8 JavaScript engine when handling     Object.observe calls on access-checked objects. A remote     attacker may exploit this to bypass the cross-origin     policy. (CVE-2015-1304)

Chromium was updated to 45.0.2454.101 to fix two security issues.

The following vulnerabilities were fixed :

  - CVE-2015-1303: Cross-origin bypass in DOM [boo#947504]

  - CVE-2015-1304: Cross-origin bypass in V8 [boo#947507]

The remote host is affected by the vulnerability described in GLSA-201603-09 (Chromium: Multiple vulnerabilities)

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

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, obtain       sensitive information, or bypass security restrictions.
  Workaround :

    There is no known workaround at this time.
