CVE-2022-1249:

A NULL pointer dereference flaw was found in pesign's 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.

Fix in 115: https://github.com/rhboot/pesign/commit/b879dda52f8122de697d145977c285fb0a022d76
