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.

It was discovered that the ContainerNode::parserRemoveChild function in Blink mishandled widget updates in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions.
(CVE-2016-1630)

It was discovered that the PPB_Flash_MessageLoop_Impl::InternalRun function in Chromium mishandled nested message loops. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions.
(CVE-2016-1631)

Multiple use-after-frees were discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-1633, CVE-2016-1634, CVE-2016-1644)

It was discovered that the PendingScript::notifyFinished function in Blink relied on memory-cache information about integrity-check occurrences instead of integrity-check successes. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass Subresource Integrity (SRI) protections. (CVE-2016-1636)

It was discovered that the SkATan2_255 function in Skia mishandled arctangent calculations. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1637)

A use-after-free was discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1641)

Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1642)

A type-confusion bug was discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-1643)

Multiple security issues were discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2843)

An invalid cast was discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2844)

It was discovered that the Content Security Policy (CSP) implementation in Blink did not ignore a URL's path component in the case of a ServiceWorker fetch. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-2845).

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, execute arbitrary code, or disclose sensitive information when visited by the victim. (CVE-2016-1630, CVE-2016-1631, CVE-2016-1632, CVE-2016-1633, CVE-2016-1634, CVE-2016-1635, CVE-2016-1636, CVE-2016-1637, CVE-2016-1638, CVE-2016-1639, CVE-2016-1640, CVE-2016-1641, CVE-2016-1642)

All Chromium users should upgrade to these updated packages, which contain Chromium version 49.0.2623.75, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

The version of Google Chrome installed on the remote Mac OS X host is prior to 49.0.2623.75. It is, therefore, affected by multiple vulnerabilities :

  - Multiple overflow conditions exist in the libpng library     in the png_set_PLTE() and png_get_PLTE() functions due     to improper handling of bit depths less than eight. A     remote attacker can exploit this, via a specially     crafted PNG image, to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2015-8126)

  - An unspecified flaw exists in Blink that allows an     attacker to bypass the same-origin policy.
    (CVE-2016-1630)

  - A bad cast flaw exists in the Extensions component that     allows an attacker to have an unspecified impact.
    (CVE-2016-1632)
