An integer overflow in FFmpeg in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android allowed a remote attacker to perform an out of bounds memory write via a crafted video file, related to ChunkDemuxer.

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

  - An integer overflow in FFmpeg in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and     57.0.2987.108 for Android allowed a remote attacker to perform an out of bounds memory write via a crafted     video file, related to ChunkDemuxer. (CVE-2017-5051)

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

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 :

  - Based on Chromium 49.0.2623.111 (the version used in     QtWebEngine 5.7.x) with security fixes from Chromium up     to version 59.0.3071.104. (5.6.2 was based on Chromium     45.0.2554.101 with security fixes from Chromium up to     version 52.0.2743.116.)

  - All other bug fixes from QtWebEngine 5.7.1 have been     backported.

See http://code.qt.io/cgit/qt/qtwebengine.git/tree/dist/changes-5.6.3?h=5.

The version of Google Chrome installed on the remote macOS host is prior to 57.0.2987.98. It is, therefore, affected by multiple vulnerabilities as referenced in the 2017_03_stable-channel-update-for-desktop advisory.

  - Incorrect handling of complex species in V8 in Google Chrome prior to 57.0.2987.98 for Linux, Windows, and     Mac and 57.0.2987.108 for Android allowed a remote attacker to execute arbitrary code via a crafted HTML     page. (CVE-2017-5030)

  - A use after free in ANGLE in Google Chrome prior to 57.0.2987.98 for Windows allowed a remote attacker to     perform an out of bounds memory read via a crafted HTML page. (CVE-2017-5031)

  - PDFium in Google Chrome prior to 57.0.2987.98 for Windows could be made to increment off the end of a     buffer, which allowed a remote attacker to potentially exploit heap corruption via a crafted PDF file.
    (CVE-2017-5032)

  - The xsltAddTextString function in transform.c in libxslt 1.1.29, as used in Blink in Google Chrome prior     to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android, lacked a check for integer     overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory     write via a crafted HTML page. (CVE-2017-5029)

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