The remote host is affected by the vulnerability described in GLSA-201709-15 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the referenced CVE identifiers 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, bypass security restrictions, or spoof content.
  Workaround :

    There is no known workaround at this time.

This update for chromium to version 61.0.3163.79 fixes several issues.

These security issues were fixed :

  - CVE-2017-5111: Use after free in PDFium (boo#1057364).

  - CVE-2017-5112: Heap buffer overflow in WebGL     (boo#1057364).

  - CVE-2017-5113: Heap buffer overflow in Skia     (boo#1057364).

  - CVE-2017-5114: Memory lifecycle issue in PDFium     (boo#1057364).

  - CVE-2017-5115: Type confusion in V8 (boo#1057364).

  - CVE-2017-5116: Type confusion in V8 (boo#1057364).

  - CVE-2017-5117: Use of uninitialized value in Skia     (boo#1057364).

  - CVE-2017-5118: Bypass of Content Security Policy in     Blink (boo#1057364).

  - CVE-2017-5119: Use of uninitialized value in Skia     (boo#1057364).

  - CVE-2017-5120: Potential HTTPS downgrade during redirect     navigation (boo#1057364).

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2017:2676 advisory.

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

    This update upgrades Chromium to version 61.0.3163.79.

    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-2017-5111, CVE-2017-5112, CVE-2017-5113, CVE-2017-5114, CVE-2017-5115,     CVE-2017-5116, CVE-2017-5117, CVE-2017-5118, CVE-2017-5119, CVE-2017-5120)

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 macOS or Mac OS X host is prior to 61.0.3163.79. It is, therefore, affected by the following vulnerabilities :

  - A use-after-free error exists in PDFium. A unauthenticated, remote     attacker can exploit this to execute arbitrary code.
    (CVE-2017-5111)

  - A heap buffer overflow condition exists in WebGL that allows an     unauthenticated, remote attacker to execute arbitrary code.
    (CVE-2017-5112)

  - A heap buffer overflow condition exists in Skia that allows an     unauthenticated, remote attacker to execute arbitrary code.
    (CVE-2017-5113)

  - An unspecified memory lifecycle issue exists in PDFium that allow     an unauthenticated, remote attacker to have an unspecified impact     (CVE-2017-5114)

  - An unspecified type confusion errors exist in V8.
    (CVE-2017-5115, CVE-2017-5116)

  - An unspecified uninitialized value flaws exist in Skia that allows     an unauthenticated, remote attacker to have an unspecified impact.
    (CVE-2017-5117, CVE-2017-5119)

  - An unspecified security bypass vulnerability exists in Blink. An     unauthenticated, remote attacker can exploit this to bypass     content security policy. (CVE-2017-5118)

  - An unspecified flaw allows HTTPS downgrade during redirection.
    (CVE-2017-5120)

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