Date: Thu, 4 Apr 2013 15:50:54 -0400 [thread overview]
Message-ID: <1d60ad5fac2f22abe5687a2325ab9c63@ladd.quanstro.net> (raw)
i wonder if the typical use of IOHDRSZ is correct.
many programs set
msize = bufsize + IOHDRSIZE
but Twrite has 2+4+8+4=18 bytes overhead, so
i think this assumption is going to lead to
6-byte buffer overruns.
