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 52.0.2743.116.

Security Fix(es) :

* Multiple flaws were found in the processing of malformed web content.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3058-1 advisory.

    An issue was discovered in Blink involving the provisional URL for an initially empty document. An     attacker could potentially exploit this to spoof the currently displayed URL. (CVE-2016-5141)

    A use-after-free was discovered in the WebCrypto implementation 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 application crash, or execute arbitrary code. (CVE-2016-5142)

    It was discovered that the devtools subsystem in Blink mishandles various parameters. An attacker could     exploit this to bypass intended access restrictions. (CVE-2016-5143, CVE-2016-5144)

    It was discovered that Blink does not ensure that a taint property is preserved after a structure-clone     operation on an ImageBitmap object derived from a cross-origin image. If a user were tricked in to opening     a specially crafted website, an attacker could potentially exploit this to bypass same origin     restrictions. (CVE-2016-5145)

    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-2016-5146, CVE-2016-5167)

    It was discovered that Blink mishandles deferred page loads. If a user were tricked in to opening a     specially crafted website, an attacker could potentially exploit this to conduct cross-site scripting     (XSS) attacks. (CVE-2016-5147)

    An issue was discovered in Blink related to widget updates. If a user were tricked in to opening a     specially crafted website, an attacker could potentially exploit this to conduct cross-site scripting     (XSS) attacks. (CVE-2016-5148)

    A use-after-free 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 application crash, or     execute arbitrary code. (CVE-2016-5150)

    A use-after-free 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 application crash, or     execute arbitrary code. (CVE-2016-5153)

    It was discovered that Chromium does not correctly validate access to the initial document. An attacker     could potentially exploit this to spoof the currently displayed URL. (CVE-2016-5155)

    A use-after-free was discovered in the event 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     application crash, or execute arbitrary code. (CVE-2016-5156)

    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 application crash, or     execute arbitrary code. (CVE-2016-5161)

    An issue was discovered with the devtools implementation. An attacker could potentially exploit this to     conduct cross-site scripting (XSS) attacks. (CVE-2016-5164)

    An issue was discovered with the devtools implementation. An attacker could potentially exploit this to     conduct cross-site scripting (XSS) attacks. (CVE-2016-5165)

The remote host is affected by the vulnerability described in GLSA-201610-09 (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.

Chromium was updated to 52.0.2743.116 to fix the following security issues: (boo#992305)

  - CVE-2016-5141: Address bar spoofing (boo#992314)

  - CVE-2016-5142: Use-after-free in Blink (boo#992313)

  - CVE-2016-5139: Heap overflow in pdfium (boo#992311)

  - CVE-2016-5140: Heap overflow in pdfium (boo#992310)

  - CVE-2016-5145: Same origin bypass for images in Blink     (boo#992320)

  - CVE-2016-5143: Parameter sanitization failure in     DevTools (boo#992319)

  - CVE-2016-5144: Parameter sanitization failure in     DevTools (boo#992315)

  - CVE-2016-5146: Various fixes from internal audits,     fuzzing and other initiatives (boo#992309)

The version of Google Chrome installed on the remote Windows host is prior to 52.0.2743.116. It is, therefore, affected by multiple vulnerabilities :

  - An overflow condition exists in PDFium due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-5139)

  - An overflow condition exists in OpenJPEG due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a heap-based     buffer overflow, resulting in a denial of service     condition or the execution of arbitrary code.
    (CVE-2016-5140)

  - A flaw exists that is triggered when nested message     loops access documents without generating a     notification. An attacker can exploit this to spoof the     address bar. (CVE-2016-5141)

  - A use-after-free error exists that allows an attacker to     dereference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-5142)

  - A flaw exists in the sanitizeRemoteFrontendUrl()     function in devtools.js due to a failure to properly     sanitize input parameters. An attacker can exploit this     to have an unspecified impact. (CVE-2016-5143)

  - A flaw exists in the loadScriptsPromise() function in     Runtime.js due to a failure to properly sanitize input     parameters. An attacker can exploit this to have an     unspecified impact. (CVE-2016-5144)

  - A flaw exists due to improper handling of specially     crafted images. An attacker can exploit this to bypass     the same-origin policy. (CVE-2016-5145)

  - Multiple unspecified high and medium severity     vulnerabilities exist, including an overflow condition     in WebRTC due to improper validation user-supplied input     when handling RTP packets. An attacker can exploit this     to cause a denial of service condition or the execution     of arbitrary code. (CVE-2016-5146)

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