Summary

Mozilla Firefox is an open source web browser.
An invalid free flaw was found in Firefox's plugin handler. Malicious web content could result in an invalid memory pointer being freed, causing Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-2755)
