"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.");
