Synopsis

Two Denial of Service vulnerabilities were discovered in Pioneers.

2.  Impact Information

Background

Pioneers (formerly gnocatan) is a clone of the popular board game "The Settlers of Catan".

Description

Roland Clobus discovered that the Pioneers server may free sessions objects while they are still in use, resulting in access to invalid memory zones (CVE-2007-5933). Bas Wijnen discovered an error when closing connections which can lead to a failed assertion (CVE-2007-6010).

Impact

A remote attacker could send specially crafted data to the vulnerable server, resulting in a Denial of Service.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Pioneers users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --ask --oneshot --verbose ">=games-board/pioneers-0.11.3-r1"
