Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the do_item_get function in items.c due to boundary error when running in verbose mode. A remote attacker can cause the service to crash via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers buffer over-read when printing to stderr.
