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
================
    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected

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

Impact

An attacker could exploit this vulnerability to execute arbitrary code
with the permissions of the user running Gld, the default user being
root.

Workaround
=========
There is no known workaround at this time.

Resolution
