buf_begin can be NULL, no DOS possible -> BOGUS1 searching for ',' is correct this works around a bug in some IE version -> BOGUS2 Previous Comments: ------------------------------------------------------------------------ [2003-03-12 03:44:37] vesely at tana dot it 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) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22657&edit=1
