Inappropriate use of www mismatch redirects in browser navigation in Google Chrome prior to 61.0.3163.79 for Mac, Windows, and Linux, and 61.0.3163.81 for Android, allowed a remote attacker to potentially downgrade HTTPS requests to HTTP via a crafted HTML page. In other words, Chrome could transmit cleartext even though the user had entered an https URL, because of a misdesigned workaround for cases where the domain name in a URL almost matches the domain name in an X.509 server certificate (but differs in the initial "www." substring).

Update to 61.0.3163.100. Security fix for 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, CVE-2017-5121, CVE-2017-5122

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 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)

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