Authentication is not required to exploit this vulnerability. The flaw exists within the ‘/opt/novell/iprint/bin/ipsmd’ component; this component communicates with ‘ilprsrvd’ which listens on TCP port 515. When handling an LPR opcode 0x01 packet type the process blindly copies user supplied data into a fixed-length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the iprint user.
Novell has issued an update to correct this vulnerability. More details can be found at:
