Description

According to its version, the installation of IBM DB2 9.7 running on the remote host is affected by the following vulnerabilities :

  • An input-validation error exists related to handling the 'ALTER MODULE' statement that allows buffer overflows. (CVE-2014-3094)

  • An error exists related to handling 'SELECT' statements with 'UNION' subqueries that allows application crashes. (CVE-2014-3095)

  • An error exists related to 'LUW' and 'ALTER TABLE' statement handling that allows application crashes. (CVE-2014-6097)

  • An error exists related to 'ALTER TABLE' statement handling that allows application crashes. (CVE-2014-6159)

Note that if a special vendor-supplied build has been installed, this may be a false positive.
