According to its version, the installation of IBM DB2 running on the remote host is either 9.7 prior to Fix Pack 11 Special Build 38744, 10.1 prior to Fix Pack 6 Special Build 38745, 10.5 prior to Fix Pack 10 Special Build 38746, or 11.1 prior to 11.1.4 Fix Pack 4a Special Build 38747. It is, therefore, affected by a local privilege escalation vulnerability due to multiple buffer overflow vulnerabilities in DB2.
