## Description

In BlueZ 5.42, a buffer overflow was observed in "commands\_dump" function
in "tools/parser/csr.c" source file. The issue exists because "commands"
array is overflowed by supplied parameter due to lack of boundary checks on
size of the buffer from frame "frm->ptr" parameter. This issue can be
triggered by processing a corrupted dump file and will result in hcidump
crash.
