The remote host is vulnerable to a buffer overflow.
The remote host is running the NOD32 antivirus software. This version of NOD32 is vulnerable to multiple stack overflows. An attacker exploiting this flaw would only need to send a malformed file to a system running the NOD32 antivirus software. Successful exploitation would result in the attacker exploiting code on the remote system.
Upgrade to version 2.70.37 or higher.
