An incorrect assumption about block structure in Blink in Google Chrome prior to 57.0.2987.133 for Mac, Windows, and Linux, and 57.0.2987.132 for Android, allowed a remote attacker to potentially exploit memory corruption via a crafted HTML page that triggers improper casting.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An incorrect assumption about block structure in Blink in Google Chrome prior to 57.0.2987.133 for Mac,     Windows, and Linux, and 57.0.2987.132 for Android, allowed a remote attacker to potentially exploit memory     corruption via a crafted HTML page that triggers improper casting. (CVE-2017-5052)

Note that Nessus relies on the presence of the package as reported by the vendor.

This update adds security fixes for CVE-2017-5052 and CVE-2017-5054, backported to Chromium 49 / QtWebEngine 5.6 by the Qt developers.

Other important changes include :

  - Based on Chromium 56.0.2924.122 with security fixes from     Chromium up to version 58.0.3029.96. (5.8.0 was based on     Chromium 53.0.2785.148 with security fixes from Chromium     up to version 55.0.2883.75.)

  - [QTBUG-54650, QTBUG-59922] Accessibility is now disabled     by default on Linux, like it is in Chrome, due to poor     options for enabling it conditionally and its heavy     performance impact. Set the environment variable     `QTWEBENGINE_ENABLE_LINUX_ACCESSIBILITY` to enable it     again.

  - [QTBUG-56531] Enabled `filesystem:` protocol handler.

  - [QTBUG-57720] Optimized incremental scene-graph     rendering in particular for software rendering.

  - [QTBUG-60049] Enabled brotli support.

  - Many bug fixes, see     https://code.qt.io/cgit/qt/qtwebengine.git/tree/dist/cha     nges-5.9.0?h=5.9 for details.

In addition, this build includes a fix for https://bugreports.qt.io/browse/QTBUG-61521 , a binary incompatibility in QtWebEngine 5.9.0 compared to 5.8.0.

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2017:0860 advisory.

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

    This update upgrades Chromium to version 57.0.2987.133.

    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-2017-5055, CVE-2017-5052, CVE-2017-5053, CVE-2017-5054, CVE-2017-5056)

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 remote host is affected by the vulnerability described in GLSA-201704-02 (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.

The version of Google Chrome installed on the remote host is prior to 57.0.2987.133, and is affected by multiple vulnerabilities :

 - A bad cast flaw exists in the 'LayoutInline::absoluteVisualRect()' function in 'layout/LayoutInline.cpp' that may allow a context-dependent attacker to have an unspecified impact. (CVE-2017-5052)
 - A use-after-free error exists in the 'PrintViewManager' class in printing'/print_view_manager.cc' that is triggered when handling previews. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5055)
 - A use-after-free error exists in 'Blink' that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5056)

This update to Chromium 57.0.2987.133 fixes the following issues (boo#1031677) :

  - CVE-2017-5055: Use after free in printing

  - CVE-2017-5054: Heap buffer overflow in V8

  - CVE-2017-5052: Bad cast in Blink

  - CVE-2017-5056: Use after free in Blink

  - CVE-2017-5053: Out of bounds memory access in V8

The following packaging changes are included :

  - No longer claim to provide browser(npapi)
