CVE: CVE-2011-3083
CWE: CWE-119
Vulnerability description: browser/profiles/profile_impl_io_data.cc in Google Chrome before 19.0.1084.46 does not properly handle a malformed ftp URL in the SRC attribute of a VIDEO element, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted web page.

Project: Chrome
