A remote overflow exists in the Tumbleweed Email Firewall. The mail decomposer module (MMSDecompose) of Tumbleweed Email Firewall fails to handle specially crafted LHA compressed archives resulting in a stack overflow. By sending a crafted mail, an attacker can potentially execute arbitrary code resulting in a loss of integrity and/or availability.
