Subject: [PATCH 4/5] Handle NULL pwdata in cms_set_pw_data()
|
|
|
|
When 12f16710ee44ef64ddb044a3523c3c4c4d90039a rewrote this function, it
|
|
didn't handle the NULL pwdata invocation from daemon.c. This leads to a
|
|
explicit NULL dereference and crash on all attempts to daemonize pesign.
|
|
|
|

|
(cherry picked from commit b879dda52f8122de697d145977c285fb0a022d76)
