Denial of Service in Google Chrome Frame Hook_Terminate (IE Plugin)

IdentifiersCVE-2013-2493CWE-20

The Hook_Terminate function in chrome_frame/protocol_sink_wrap.cc in the Google Chrome Frame plugin before 26.0.1410.28 for Internet Explorer does not properly handle attach tab requests. Specifically, it fails to correctly process an _blank value for the target attribute of an A element, which can be exploited by a user-assisted remote attacker to trigger a denial of service (application crash).

Impact

What an attacker gets, and what they’ve been doing with it.
