CVE-2019-4448

Estado: ModificadaAlta (7.8)—

IBM DB2 High Performance Unload load for LUW 6.1, 6.1.0.1, 6.1.0.1 IF1, 6.1.0.2, 6.1.0.2 IF1, and 6.1.0.1 IF2 db2hpum and db2hpum_debug binaries are setuid root and have built-in options that allow an low privileged user the ability to load arbitrary db2 libraries from a privileged context. This results in arbitrary code being executed with root authority. IBM X-Force ID: 163489.
