Package: ipmitool Version: 1.8.18-1 Hi, i had problems with ipmitool 1.8.14 which segfaulted in fwum upgrade. I build 1.8.18 on a Debian/Jessie to try a newer version which also broke.
Core was generated by `src/ipmitool fwum upgrade /tmp/Linux/X8DT3303.ima'.
Program terminated with signal SIGSEGV, Segmentation fault.

It seems the firmware file buffer is statically allocated on the stack with
512*1024
but then the whole file is read to it.
