A vulnerability in the way Novell NetMail handles NMAP “STOR” commands may cause a buffer overflow that may allow remote execution of arbitrary code.
Novell NetMail’s implementation of the Network Messaging Application Protocol (NMAP) contains a buffer overflow that may occur when processing parameters supplied to the “STOR” command. An attacker must login to an affected system in order to take advantage of this vulnerability. The vulnerable daemon, nmapd.exe, binds to port 689/tcp.
A remote, authenticated attacker may be able to execute arbitrary code or cause a denial-of-service condition.
Update
Novell has released an update to address this issue. See Novell document 3096026 for more details.
Block port 689/tcp
As a workaround, system administrators can use a firewall to block port 689/tcp at an appropriate network border, thus preventing external attackers from accessing the vulnerable nmapd.exe daemon. Note that this will not prevent an attack from within the local network.
