Basic Technical Details
************************************************************************
Proof Of Concept Status : SNO has proof of concept. 

Low Level Description   : Ebola is a AntiVirus scanning daemon system 
which offers to improve considerably the performance of scanning systems 
such as AMaViS, Inflex and other such programs which require ondemand 
scanning from various AV engines.

The Ebola daemon contains a remotely exploitable buffer overflow in its
authentication sequence. 

This issue is caused by the handle_PASS() function in ebola.c 

char outstr[100];
...
if (passwd) {
   if (PASS_authenticate(username, passwd) == _PASS_OK) {
	sprintf(outstr,"PASS NOT ACCEPTED for user \"%s\", 
        pass \"%s\".\n",username,passwd);
...

Please upgrade to version 0.1.5 of the ebola daemon. 

Vendor Status           : Paul L Daniels promptly responded to this issue,
