The version of Google Chrome installed on the remote Windows host is prior to 49.0.2623.108. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in Google V8 that     allows an attacker to crash the application, resulting     in a denial of service. (CVE-2016-1646)

  - A use-after-free error exists in the Navigation     component that allows an attacker to dereference already     freed memory, resulting in the execution of arbitrary     code. (CVE-2016-1647)

  - A use-after-free error exists in the Extensions     component that allows an attacker to dereference already     freed memory, resulting in the execution of arbitrary     code. (CVE-2016-1648)

  - An overflow condition exists in libANGLE due to improper     validation of user-supplied input. An attacker can     exploit this to execute arbitrary code. (CVE-2016-1649)

  - An unspecified flaw exists in the pageCapture extension     that allows an attacker to have an unspecified impact.
    (CVE-2016-1650)

  - A denial of service vulnerability exists in PDFium due     to improper handling of file names. An attacker can     exploit this to crash the application, resulting in a     denial of service.

Chromium was updated to 49.0.2623.110 to fix the following security issues :

  - CVE-2016-1646: Out-of-bounds read in V8

  - CVE-2016-1647: Use-after-free in Navigation

  - CVE-2016-1648: Use-after-free in Extensions

  - CVE-2016-1649: Buffer overflow in libANGLE

  - CVE-2016-1650: Various fixes from internal audits,     fuzzing and other initiatives

  - CVE-2016-3679: Multiple vulnerabilities in V8 fixed at     the tip of the 4.9 branch (currently 4.9.385.33)

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.

Several vulnerabilities have been discovered in the chromium web browser.

  - CVE-2016-1646     Wen Xu discovered an out-of-bounds read issue in the v8     library.

Multiple vulnerabilities in V8 fixed at the tip of the 4.9 branch

The version of Google Chrome installed on the remote Mac OS X host is prior to 49.0.2623.108. It is, therefore, affected by multiple vulnerabilities :

    (CVE-2016-1650)

  - A denial of service vulnerability exists in PDFium due     to improper handling of file names. An attacker can     exploit this to crash the application, resulting in a     denial of service.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2955-1 advisory.

    A use-after-free was discovered when responding synchronously to permission requests. 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-2016-1578)

    An out-of-bounds read 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.
    (CVE-2016-1646)

    A use-after-free was discovered in the navigation implementation in Chromium in some circumstances. 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-2016-1647)

    A buffer overflow was discovered in ANGLE. 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-2016-1649)

    An out-of-bounds write 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 with the privileges of the sandboxed renderer process. (CVE-2016-1653)

    An invalid read was discovered in the media subsystem 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. (CVE-2016-1654)

    It was discovered that frame removal during callback execution could trigger a use-after-free 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 renderer process. (CVE-2016-1655)

    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-2016-1659)

    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-2016-3679)
