Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, does not request user confirmation before continuing a large series of downloads, which allows user-assisted remote attackers to cause a denial of service (resource consumption) via a crafted web site.

The remote host is affected by the vulnerability described in GLSA-201208-03 (Chromium: Multiple vulnerabilities)

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

    A remote attacker could entice a user to open a specially crafted web       site using Chromium, possibly resulting in the execution of arbitrary       code with the privileges of the process, a Denial of Service condition,       disclosure of sensitive information, or other unspecified impact.
  Workaround :

    There is no known workaround at this time.
