4Subject: [PATCH] netscreen: do bounds checking for each byte of packet data.
5
6Make sure each byte we add to the packet data from the file fits in the
7buffer, rather than stuffing bytes into the buffer and checking
8afterwards.
9
10This prevents a buffer overflow.
11
12Fixes #19404, which was filed as part of Trend Micro's Zero Day
13Initiative as ZDI-CAN-22164.
14
15While we're at it, expand a comment and make error messages give some
16more detail.
