Description

According to its version, the installation of IBM DB2 9.7 running on the remote host is prior to Fix Pack 5. It is, therefore, affected by multiple denial of service vulnerabilities :

  • On Unix and Unix-like systems with both the Self Tuning Memory Manager (STMM) feature enabled and the
