CVE-2003-0899

This exploit targets a buffer overflow vulnerability in thttpd's defang() function by sending a maliciously crafted HTTP GET request with an overly long path. The exploit is designed to cause a denial-of-service (DoS) by crashing the thttpd daemon.

The code is a snippet of the vulnerable `defang()` function from thttpd, which lacks bounds checking and can lead to a buffer overflow. It does not contain an exploit but explains the vulnerability.
