Parfait reported following: Error: Buffer overrun Buffer overflow (CWE 120): In pointer dereference of s[i] with index 'i' Pointer size is 768 bytes, index is 768 at line 105 of httpd-2.2.24/support/htdigest.c in function 'get_line'. called at line 258 in function 'main' with s = line. This seems to be true also for HEAD.
