An issue was discovered in atftpd in atftp 0.7.1. A remote attacker may
send a crafted packet triggering a stack-based buffer overflow due to an
insecurely implemented strncpy call. The vulnerability is triggered by
sending an error packet of 3 bytes or fewer. There are multiple instances
of this vulnerable strncpy pattern within the code base, specifically
within tftpd_file.c, tftp_file.c, tftpd_mtftp.c, and tftp_mtftp.c.
