Mozilla Firefox is an open source Web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Several use-after-free flaws were found in Firefox. Visiting a web page containing malicious content could result in Firefox executing arbitrary code with the privileges of the user running Firefox. (CVE-2010-0175, CVE-2010-0176, CVE-2010-0177) A flaw was found in Firefox that could allow an applet to generate a drag and drop action from a mouse click. Such an action could be used to execute arbitrary JavaScript with the privileges of the user running Firefox. (CVE-2010-0178) A privilege escalation flaw was found in Firefox when the Firebug add-on is in use. The XMLHttpRequestSpy module in the Firebug add-on exposes a Chrome privilege escalation flaw that could be used to execute arbitrary JavaScript with the privileges of the user running Firefox. (CVE-2010-0179) Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox.
