Synopsis

Dillo is vulnerable to a format string bug, which may result in the execution of arbitrary code.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-client/dillo	< 0.8.3-r4	>= 0.8.3-r4	All supported architectures

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

There is no known workaround at this time.

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/dillo-0.8.3-r4"
