An update for chromium-browser is now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

This update upgrades Chromium to version 50.0.2661.102.

Security Fix(es) :

* Multiple 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-2016-1667, CVE-2016-1668, CVE-2016-1669, CVE-2016-1670)

The version of Google Chrome installed on the remote Windows host is prior to 50.0.2661.102. It is, therefore, affected by multiple vulnerabilities :

  - A same-origin bypass vulnerability exists in DOM due to     scripts being permitted run while a node is being     adopted. A context-dependent attacker can exploit this     to bypass the same-origin policy. (CVE-2016-1667)

  - A same-origin bypass vulnerability exists due to a flaw     in the Blink V8 bindings. A context-dependent attacker     can exploit this to bypass the same-origin policy.
    (CVE-2016-1668)

  - An overflow condition exists in V8 due to improper     validation of user-supplied input. A context-dependent     attacker can exploit this to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-1669)

  - A race condition exists in the loader related to the use     of ids. An attacker can exploit this to have an     unspecified impact. (CVE-2016-1670)

  - Multiple type confusion errors exist in the bundled     version of Adobe Flash that allow an attacker to execute     arbitrary code. (CVE-2016-1105, CVE-2016-4117)

  - Multiple use-after-free errors exist in the bundled     version of Adobe Flash that allow an attacker to execute     arbitrary code. (CVE-2016-1097, CVE-2016-1106,     CVE-2016-1107, CVE-2016-1108, CVE-2016-1109,     CVE-2016-1110, CVE-2016-4108, CVE-2016-4110,     CVE-2016-4121)

  - A heap buffer overflow condition exists in the bundled     version of Adobe Flash that allows an attacker to     execute arbitrary code. (CVE-2016-1101)

  - An unspecified buffer overflow exists in the bundled     version of Adobe Flash that allows an attacker to     execute arbitrary code. (CVE-2016-1103)

  - Multiple memory corruption issues exist in the bundled     version of Adobe Flash that allow an attacker to execute     arbitrary code. (CVE-2016-1096, CVE-2016-1098,     CVE-2016-1099, CVE-2016-1100, CVE-2016-1102,     CVE-2016-1104, CVE-2016-4109, CVE-2016-4111,     CVE-2016-4112, CVE-2016-4113, CVE-2016-4114,     CVE-2016-4115, CVE-2016-4120, CVE-2016-4160,     CVE-2016-4161, CVE-2016-4162, CVE-2016-4163)

  - A flaw exists in the bundled version of Adobe Flash when     loading dynamic-link libraries. An attacker can exploit     this, via a specially crafted .dll file, to execute     arbitrary code. (CVE-2016-4116)

The remote host is affected by the vulnerability described in GLSA-201605-02 (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.

An out of bounds write 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. (CVE-2016-1660)

It was discovered that Blink assumes that a frame which passes same-origin checks is local in some cases. 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. (CVE-2016-1661)

A use-after-free was discovered in the V8 bindings 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. (CVE-2016-1663)

It was discovered that the JSGenericLowering class in V8 mishandles comparison operators. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1665)

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.
(CVE-2016-1666)

It was discovered that the TreeScope::adoptIfNeeded function in Blink does not prevent script execution during node-adoption operations. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2016-1667)

It was discovered that the forEachForBinding in the V8 bindings in Blink uses an improper creation context. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2016-1668)

A buffer overflow was discovered in V8. 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. (CVE-2016-1669)

A race condition was discovered in ResourceDispatcherHostImpl in Chromium. An attacker could potentially exploit this to make arbitrary HTTP requests. (CVE-2016-1670).

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.
