Background

Dillo is a small and fast multi-platform web browser based on GTK+.

Description

Gentoo Linux developer Tavis Ormandy found a format string bug in Dillo's handling of messages in a_Interface_msg().

Impact

An attacker could craft a malicious web page which, when accessed using Dillo, would trigger the format string vulnerability and potentially execute arbitrary code with the rights of the user running Dillo.

Workaround
