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

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
