<bug_description>Exim is an well-known open-source Mail Transfer Agent (MTA) for Unix systems. It has been discovered that there is a format string vulnerability in the daemon_go() function. This attack is possible by sending the malicous requests over the command line. An attacker may run arbritrary code and get root privileges. It should be noted that the execution of the affected function is limited to the user defined as exim-admin-user. This one must be defined at compile time.</bug_description>
<bug_solution>The vendor released patches to fix the vulnerability. Users with affected systems should update as soon as possible. The Exim Patch for 3.36 can be found at http://downloads.securityfocus.com/vulnerabilities/patches/exim336.patch and for 4.10 at http://downloads.securityfocus.com/vulnerabilities/patches/exim410.patch.</bug_solution>
