The SkRegion::readFromMemory function in core/SkRegion.cpp in Skia, as used in Google Chrome before 51.0.2704.79, does not validate the interval count, which allows remote attackers to cause a denial of service (out-of-bounds read) via crafted serialized data.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2992-1 advisory.

    An unspecified security issue was discovered in Blink. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit this to bypass same-origin restrictions.
    (CVE-2016-1673)

    An issue was discovered with Document reattachment in Blink in some circumstances. If a user were tricked     in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-     origin restrictions. (CVE-2016-1675)

    A type confusion bug was discovered in V8. If a user were tricked in to opening a specially crafted     website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1677)

    A heap overflow 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 (application crash) or execute     arbitrary code. (CVE-2016-1678)

    A use-after-free was discovered in the V8ValueConverter 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 (application crash) or execute arbitrary code. (CVE-2016-1679)

    A use-after-free was discovered in Skia. If a user were tricked in to opening a specially crafted website,     an attacker could potentially exploit this to cause a denial of service (application crash) or execute     arbitrary code. (CVE-2016-1680)

    A security issue was discovered in ServiceWorker registration in Blink in some circumstances. If a user     were tricked in to opening a specially crafted website, an attacker could potentially exploit this to     bypass Content Security Policy (CSP) protections. (CVE-2016-1682)

    An out-of-bounds memory access was discovered in libxslt. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit this to cause a denial of service (application     crash) or execute arbitrary code. (CVE-2016-1683)

    An integer overflow was discovered in libxslt. If a user were tricked in to opening a specially crafted     website, an attacker could potentially exploit this to cause a denial of service (application crash or     resource consumption). (CVE-2016-1684)

    An out-of-bounds read was discovered in the regular expression implementation 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 (application crash). (CVE-2016-1688)

    A heap overflow was discovered 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 (application crash) or     execute arbitrary code. (CVE-2016-1689)

    A heap overflow was discovered in Skia. If a user were tricked in to opening a specially crafted website,     an attacker could potentially exploit this to cause a denial of service (application crash) or execute     arbitrary code. (CVE-2016-1691)

    It was discovered that Blink permits cross-origin loading of stylesheets by a service worker even when the     stylesheet download has an incorrect MIME type. If a user were tricked in to opening a specially crafted     website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1692)

    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 (application crash) or execute arbitrary code. (CVE-2016-1695, CVE-2016-1703)

    It was discovered that Blink does not prevent frame navigation during DocumentLoader detach operations. If     a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this     to bypass same-origin restrictions. (CVE-2016-1697)

    A parameter sanitization bug was discovered in the devtools subsystem in Blink. An attacker could     potentially exploit this to bypass intended access restrictions. (CVE-2016-1699)

    An out-of-bounds read was discovered in Skia. If a user were tricked in to opening a specially crafted     website, an attacker could potentially exploit this to cause a denial of service (application crash).
    (CVE-2016-1702)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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