LIBCGI is prone to an overflow condition. The program fails to properly sanitize user-supplied input resulting in a stack-based buffer overflow. With a specially crafted request which exploits inadequate bounds check in 'parse_field()' function in the 'cgi_lib.c', a remote attacker can potentially cause corrupt memory.
