Description Tomas Hoger 2012-07-16 11:59:59 EDT
An uninitialized pointer use flaw was found in IcedTea-Web web browser plugin.  A malicious web page could use this flaw make IcedTea-Web browser plugin pass invalid pointer to a web browser.  Depending on the browser used, it may cause the browser to crash or possibly execute arbitrary code.

The get_cookie_info() and get_proxy_info() call getFirstInTableInstance() with the instance_to_id_map hash as a parameter.  If instance_to_id_map is empty (which can happen when plugin was recently removed), getFirstInTableInstance() returns an uninitialized pointer.
