The parser in Google V8, as used in Google Chrome before 53.0.2785.113, mishandles scopes, which allows remote attackers to obtain sensitive information from arbitrary memory locations via crafted JavaScript code.

This update updates QtWebEngine to a snapshot from the Qt 5.6 LTS (long-term support) branch. This is a snapshot of the QtWebEngine that will be included in the bugfix and security release Qt 5.6.3, but only the QtWebEngine component is included in this update.

The update fixes the following security issues in QtWebEngine 5.6.2:
CVE-2016-5133, CVE-2016-5147, CVE-2016-5153, CVE-2016-5155, CVE-2016-5161, CVE-2016-5166, CVE-2016-5170, CVE-2016-5171, CVE-2016-5172, CVE-2016-5181, CVE-2016-5185, CVE-2016-5186, CVE-2016-5187, CVE-2016-5188, CVE-2016-5192, CVE-2016-5198, CVE-2016-5205, CVE-2016-5207, CVE-2016-5208, CVE-2016-5214, CVE-2016-5215, CVE-2016-5221, CVE-2016-5222, CVE-2016-5224, CVE-2016-5225, CVE-2016-9650, CVE-2016-9651, CVE-2016-9652, CVE-2017-5006, CVE-2017-5007, CVE-2017-5008, CVE-2017-5009, CVE-2017-5010, CVE-2017-5012, CVE-2017-5015, CVE-2017-5016, CVE-2017-5017, CVE-2017-5019, CVE-2017-5023, CVE-2017-5024, CVE-2017-5025, CVE-2017-5026, CVE-2017-5027, CVE-2017-5029, CVE-2017-5033, CVE-2017-5037, CVE-2017-5044, CVE-2017-5046, CVE-2017-5047, CVE-2017-5048, CVE-2017-5049, CVE-2017-5050, CVE-2017-5051, CVE-2017-5059, CVE-2017-5061, CVE-2017-5062, CVE-2017-5065, CVE-2017-5067, CVE-2017-5069, CVE-2017-5070, CVE-2017-5071, CVE-2017-5075, CVE-2017-5076, CVE-2016-5078, CVE-2017-5083, and CVE-2017-5089.

Other important changes include :

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.

Node.js v6.9.0 LTS contains the following security fixes, specific to v6.x :

Disable auto-loading of openssl.cnf: Don't automatically attempt to load an OpenSSL configuration file, from the OPENSSL_CONF environment variable or from the default location for the current platform. Always triggering a configuration file load attempt may allow an attacker to load compromised OpenSSL configuration into a Node.js process if they are able to place a file in a default location.

Patched V8 arbitrary memory read (CVE-2016-5172): The V8 parser mishandled scopes, potentially allowing an attacker to obtain sensitive information from arbitrary memory locations via crafted JavaScript code. This vulnerability would require an attacker to be able to execute arbitrary JavaScript code in a Node.js process.

Create a unique v8_inspector WebSocket address: Generate a UUID for each execution of the inspector. This provides additional security to prevent unauthorized clients from connecting to the Node.js process via the v8_inspector port when running with --inspect. Since the debugging protocol allows extensive access to the internals of a running process, and the execution of arbitrary code, it is important to limit connections to authorized tools only. Note that the v8_inspector protocol in Node.js is still considered an experimental feature. Vulnerability originally reported by Jann Horn.

All of these vulnerabilities are considered low-severity for Node.js users, however, users of Node.js v6.x should upgrade at their earliest convenience.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3091-1 advisory.

    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     application crash, or execute arbitrary code. (CVE-2016-5170)

    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     application crash, or execute arbitrary code. (CVE-2016-5171)

    An issue was discovered in V8. If a user were tricked in to opening a specially crafted website, an     attacker could potentially exploit this to ontain sensitive information from arbitrary memory locations.
    (CVE-2016-5172)

    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-2016-5175, CVE-2016-5178)

    A use-after-free 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 application crash, or execute     arbitrary code. (CVE-2016-5177)

    It was discovered that Chromium does not ensure the recipient of a certain IPC message is a valid     RenderFrame or RenderWidget. An attacker could potentially exploit this to cause a denial of service via     application crash, or execute arbitary code. (CVE-2016-7549)

Several vulnerabilities have been discovered in the chromium web browser.

  - CVE-2016-5170     A use-after-free issue was discovered in Blink/Webkit.

  - CVE-2016-5171     Another use-after-free issue was discovered in     Blink/Webkit.

  - CVE-2016-5172     Choongwoo Han discovered an information leak in the v8     JavaScript library.

The version of Google Chrome installed on the remote Mac OS X host is prior to 53.0.2785.113. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists in the file     bindings/modules/v8/V8BindingForModules.cpp that allows     an unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-5170)

  - A use-after-free error exists in Blink that is related     to window constructors being callable. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2016-5171)

  - An arbitrary memory read error exists in V8 that allows     an unauthenticated, remote attacker to disclose     sensitive memory information. (CVE-2016-5172)

  - A flaw exists due to improper handling of specially     crafted web pages. An unauthenticated, remote attacker     can exploit this to load JavaScript extension resources,     which may then be used to perform unauthorized actions.
    (CVE-2016-5173)

  - A flaw exists that is triggered when in fullscreen mode,     in file ui/cocoa/browser_window_controller_private.mm,     that results in a failure to suppress popups.
    (CVE-2016-5174)

  - An unspecified flaw exists that allows an attacker to     impact confidentiality, integrity, and availability.
    (CVE-2016-5175)

  - A flaw exists due to improper handling of IPC messages     for dead routing IDs. An authenticated, remote attacker     can exploit this to execute arbitrary code.
    (CVE-2016-5175)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to bypass the     SafeBrowsing protection mechanism. (CVE-2016-5176)

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 Windows host is prior to 53.0.2785.113. It is, therefore, affected by multiple vulnerabilities :
