The JavaScript Engine in the Mozilla 1.7 application (see mozilla(1)) contains multiple memory corruption vulnerabilities (see below for details)

1. Impact

The JavaScript Engine in the Mozilla 1.7 application (see mozilla(1)) contains multiple memory corruption vulnerabilities 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 15 separate memory corruption issues:

• http://www.mozilla.org/security/announce/2006/mfsa2006-65.html

This Sun Alert corresponds to the 10 JavaScript engine issues described in the Mozilla advisory under CVE-2006-5748.

Note that of these 10 vulnerabilities, Mozilla 1.7 is only affected by the following six issues:
