"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 36621,
10.1 prior to Fix Pack 6 Special Build 36610, 10.5 prior to Fix Pack 8
Special Build 36605, or 11.1.2 prior to Fix Pack 2. It is, therefore,
affected by the following vulnerabilities :

  - A buffer overflow condition exists due to improper
    validation of user-supplied input. A local attacker can
    exploit this to overwrite DB2 files or cause a denial of
    service condition. (CVE-2017-1105)

  - A stack-based buffer overflow condition exists in the
    Command Line Process (CLP) due to improper bounds
    checking. A local attacker can exploit this to execute
    arbitrary code. (CVE-2017-1297)");
