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.

NOTE: The vendor has concluded that the weakness is caused due to an infinite recursion which causes a stack overflow, which only can be exploited to crash a vulnerable browser and cannot be exploited for code execution.
