DESCRIPTION:
Tom Ferris has discovered a weakness in Firefox, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The weakness is caused due to an error in the handling of overly
large size attributes in the "Iframe" tag. This can be exploited to
crash a vulnerable browser via a specially crafted "Iframe" tag on a
malicious web site.

The weakness has been confirmed in version 1.0.7 on Fedora Core 4
(Linux). Other versions and platforms may also be affected.

SOLUTION:
Do not browse untrusted web sites.
