the USN-2860-1 advisory.

    A race condition was discovered in the MutationObserver implementation 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 render process.
    (CVE-2015-6789)

    An issue was discovered with the page serializer in Blink. If a user were tricked in to opening a
    specially crafted website, an attacker could potentially exploit this to inject arbitrary script or HTML.
    (CVE-2015-6790)

    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-2015-6791)

    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-2015-8548)

    An integer overflow was discovered in the WebCursor::Deserialize function 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, or execute arbitrary code with the privileges of the user
    invoking the program. (CVE-2015-8664)

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
