Date of Resolved Release
11-OCT-2007

Impact

A number of memory corruption vulnerabilities have been found in the Mozilla application 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).

The following Mozilla advisory describes ten separate memory corruption issues:
