|
1) Introduction
|
|
===============
|
|
|
|
|
|
phrelay and phindows/phditto are based on a private protocol that
|
|
allows to use the Photon graphical environment of the server (through
|
|
the phrelay inetd program) on another machine (phindows, phditto and
|
|
any other client).

--------------------------------
|
|
A] bpe_decompress stack overflow
|
|
--------------------------------
|
|
|
|
The BPE (byte pair encoding) compression uses two stack buffers of 256
|
|
bytes called "left" and "right".
|
|
The bpe_decompress function used in all the client/server programs of
|
|
this protocol is affected by a stack based buffer-overflow caused by
|
|
the lack of checks on the data sequentially stored in these two
|
|
buffers.
|
|
|
|
|
|
---------------------------------
|
|
B] Photon Session buffer overflow
|
|
---------------------------------
|
|
|
|
Buffer-overflow affecting phrelay in the handling of the device file
|
|
specified by the client as existing Photon session.
|
|
|
|
|
|
Note: considering that phrelay is not enabled by default and allows to
|
|
connect without authentication directly to /dev/photon (the screen
|
|
visible phisically on the machine) and phindows/phditto must be
|
|
manually pointed to the malicious host for exploiting bug A, this
|
|
advisory must be considered only a case study and nothing more.

A]
|
|
at the moment I don't know how to call bpe_decompress on phrelay but I
|
|
have verified that the bpe_decompress function is vulnerable at 100%.
|
|
the following test works only on phindows/phditto (the proof-of-concept
|
|
acts as a server):
|
|
|
|
udpsz -C "a5 00 00 01 0000 ffff" -b A -l 0 -T -1 0 4868 1+7+0xffff
|
|
|
|
B]
|
|
udpsz -C "a5 10 00 00 0000 ffff 1400000008040100000000008002e0010000000000000000000000000000" -b A -T SERVER 4868 1+7+0xffff
