Mozilla Firefox: Potential remote code execution The Mozilla Firefox 1.5 line is vulnerable to a buffer overflow in the JavaScript extension which may in theory lead to remote execution of arbitrary code. mozilla-firefox 2006-05-06 2006-05-06 131138 remote 1.5.0.3 1.5 1.5.0.3 1.5.0.3 1.5 1.5.0.3

Mozilla Firefox is the next-generation web browser from the Mozilla project.

Martijn Wargers and Nick Mott discovered a vulnerability when rendering malformed JavaScript content. The Mozilla Firefox 1.0 line is not affected.

If JavaScript is enabled, by tricking a user into visiting a malicious web page which would send a specially crafted HTML script that contains references to deleted objects with the "designMode" property enabled, an attacker can crash the web browser and in theory manage to execute arbitrary code with the rights of the user running the browser.

There is no known workaround at this time.

All Mozilla Firefox 1.5 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.5.0.3"

All Mozilla Firefox 1.5 binary users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-1.5.0.3" CVE-2006-1993 koon falco falco
