MMFTPD SysLog Format String Vulnerability

mmftpd is a freely available, open source FTP server for Linux operating systems.

A syslog call in the program which logs user-supplied information could be exploited to print to specified places in memory, including potentially overwriting the return address of a function and executing arbitrary code.
