Netscape is a freely available web browser distributed by Netscape Communications, and available for various platforms. This vulnerability is known to affect those installations on the Linux platform.

A buffer overflow has been reported in the Composer function of Netscape. When an HTML page with a Font Face field of arbitrary length is edited using Netscape Composer, a memory corruption bug may occur that could allow the overwriting of process memory, and execution of attacker supplied code.
