DOS issue in Astaro Version 7 packet filter reporting

Risk: Medium
Local: Yes
Remote: No

I have details about the DOS issue on my blog with links to the Astaro forums. Version affected: ALL Version 7 systems. This is easily reproducible. Just setup a BT client behind the astaro and do not setup a packetfilter and NAT rule for the BT traffic. This way all the incoming return traffic is blocked. Go download something like the Centos DVD torrent. Some machine(like mine) are easy to bring down. Others take a time longer. The file will peg the cpu for an exorbitant amount of time. Before 7.006 it would take the machine offline. 7.006 partially mitigates in my testing but not fully. For the pop3 Proxy if you set an attachment size limit, any attachments over that size are NOT scanned and allowed to pass through instead of being quarantined. These are not critical events but are issues nonetheless. -- My "Foundation" verse: Isa 54:17 No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn.
