Description:   A vulnerability was reported in the Mozilla browser. A remote user may be able to execute arbitrary code on the target user's system.

A vulnerability was reported in the S/MIME implementation in the NSS security suite that ships with Mozilla 1.4. A remote user can reportedly send a specially crafted S/MIME email message that contains certain unexpected ASN.1 constructs to cause the target user's browser to crash or arbitrary code to be executed on the target user's system.

This was demonstrated using the NISCC test suite, the report said.

NSS version 3.9 reportedly corrects these problems.
