The remote host is affected by the vulnerability described in GLSA-201502-13 (Chromium: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Chromium. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to cause a Denial of Service condition,       gain privileges via a filesystem: URI, or have other unspecified impact.
  Workaround :

    There is no known workaround at this time.

Updated chromium-browser packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash or, potentially, execute arbitrary code with the privileges of the user running Chromium. (CVE-2014-7923, CVE-2014-7924, CVE-2014-7925, CVE-2014-7926, CVE-2014-7927, CVE-2014-7928, CVE-2014-7929, CVE-2014-7930, CVE-2014-7931, CVE-2014-7932, CVE-2014-7933, CVE-2014-7934, CVE-2014-7935, CVE-2014-7936, CVE-2014-7937, CVE-2014-7938, CVE-2014-7939, CVE-2014-7940, CVE-2014-7941, CVE-2014-7942, CVE-2014-7943, CVE-2014-7944, CVE-2014-7945, CVE-2014-7946, CVE-2014-7947, CVE-2014-7948)

All Chromium users should upgrade to these updated packages, which contain Chromium version 40.0.2214.91, which corrects these issues.
After installing the update, Chromium must be restarted for the changes to take effect.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2476-1 advisory.

    Several memory corruption bugs were discovered in ICU.

(CVE-2014-7923,     CVE-2014-7926)

    A use-after-free was discovered in the IndexedDB implementation. 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-2014-7924)

    A use-after free was discovered in the WebAudio implementation in Blink.

    (CVE-2014-7938)

    It was discovered that ICU did not initialize memory for a data structure correctly.

    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-2015-1205)

    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.
