The JavaScript Engine in the Mozilla 1.7 application (see mozilla(1)) contains a vulnerability which may allow a remote user who is able to create a web page which is visited by a local user using the Mozilla browser, or who sends a specially crafted email that is read by a local user using Mozilla, to either cause the Mozilla application to crash or execute arbitrary code with the privileges of the user running Mozilla. The ability of a remote user to cause the Mozilla application to crash is a type of Denial of Service (DoS).
