Mozilla CSS integer overflow vulnerability

Overview

Mozilla products contain an integer overflow that could allow a remote, unauthenticated attacker to execute arbitrary code.

Description

Cascading Style Sheets

CSS is a mechanism for adding style to web documents.

The problem

Mozilla products contain an integer overflow in the CSS letter spacing property. This may allow a remote attacker to manipulate memory allocation routines to create an undersized buffer. When data is copied to this buffer, a heap-based buffer overflow may occur.

For a list of affected, products refer to Mozilla Foundation Security Advisory 2006-22.

Impact

If an attacker can persuade a user to access a specially crafted web page, that attacker may be able to execute arbitrary code.
