According to its version, the installation of IBM DB2 9.5 running on the remote host is prior or equal to Fix Pack 9 or 10. It is, therefore, reportedly affected by one or more of the following vulnerabilities :
An unspecified error exists related to handling malformed certificate chains that could allow denial of service attacks. (CVE-2013-6747)
A build error exists related to libraries in insecure locations that could allow a local user to carry out privilege escalation attacks. Note this issue does not affect the application when running on Microsoft Windows operating systems. (CVE-2014-0907)
An unspecified error exists related to the TLS implementation that could allow certain error cases to cause 100% CPU utilization. (CVE-2014-0963)
