A NULL pointer dereference flaw was found in pesigns cms_set_pw_data() function of the cms_common.c file. The function fails to handle the NULL pwdata invocation from daemon.c, which leads to an explicit NULL dereference and crash on all attempts to daemonize pesign.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
