CVE-2019-4447

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_debug is a setuid root binary which trusts the PATH environment variable. A low privileged user can execute arbitrary commands as root by altering the PATH variable to point to a user controlled location. When a crash is induced the trojan gdb command is executed. IBM X-Force ID: 163488.
