Another security flaw has been found in Mozilla Firefox. This time in Firefox 1.0.7, which is a security update released last month.
According to Whitedust Security, the flaw will need patching as soon as possible. Secunia reports the exploit is 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.
Other version may also be affected.
