Bug #2276

Updated by Victor Julien about 7 years ago

An empty value for coredump.max-dump in the config-file leads to a segfault because of a NULL-pointer dereference in CoredumpLoadConfig(). 

 Here is a configuration example: 

 coredump.max-dump: [] 

 This will let suricata crash with a segfault.
