What is CVE-2019-4448?

The IBM DB2 High Performance Unload for LUW versions 6.1 and its updates present a vulnerability where the db2hpum and db2hpum_debug binaries are setuid root. This configuration enables a low privileged user to exploit built-in options, allowing them to load arbitrary DB2 libraries within a privileged context. Consequently, this may lead to the execution of arbitrary code with elevated root permissions, posing a significant security risk.
