Hi,
watch out rfc1867.c around line 342, in function
next_line() there is (was?) the following code:
if (ptr) {
/* ... */
} else {
/* ... */
line[self->bufsize] = 0;
self->buf_begin = ptr; /* <=== */
self->bytes_in_buffer = 0;
}
ptr is obviously NULL, buf_begin should never be NULL
or the program may crash. So this is a potential
vulnerability for DOS attackers who submit long lines.
Since you're there, would you mind to check why at line
721, in the rfc1867_post_handler function, there is
boundary_end = strchr(boundary, ',');
Shouldn't it be ';' (semicolon) rather than ',' (comma)?
(Just wandering)
