Synopsis
========

Gld contains several serious vulnerabilities, potentially resulting in
the execution of arbitrary code as the root user.

Background
==========

Gld is a standalone greylisting server for Postfix.

Affected packages

Description
===========

dong-hun discovered several buffer overflows in server.c, as well as
several format string vulnerabilities in cnf.c.

Impact

with the permissions of the user running Gld, the default user being
root.

Workaround
