Submit #756036: Zaher1307 TinyWebServer >0.0.0 Stack-based Buffer Overflowinfo

TitelZaher1307 TinyWebServer >0.0.0 Stack-based Buffer Overflow
BeschreibungTinyWebServer is a simple web server that combines many of the ideas such as process control, Unix I/O, the sockets interface, and HTTP. This code is vulnerable to CWE-787: Out-of-bounds Write (Stack Buffer Overflow) due to the use of the unsafe sprintf() function in the client_error() function. The function processes a user-controlled HTTP request URI. When a file is not found (stat() returns -1), the error handling functionclient_error()is called with the filename (which contains the user-controlled URI) as the cause parameter. The function then uses sprintf() to format this unvalidated input into a fixed-size stack buffer linebuf[8192] without any boundary checking.
