Gogs vulnerable to improper PAM authorization handling

Impact

Expired PAM accounts and accounts with expired passwords are continued to be seen as valid. Installations use PAM as authentication sources are affected.

Patches

Expired PAM accounts and accounts with expired passwords are no longer being seen as valid. Users should upgrade to 0.12.5 or the latest 0.13.0+dev.

Workarounds

In addition to marking PAM accounts as expired, also disable/lock them. Running usermod -L <username> will add an exclamation mark to the password hash and would result in wrong passwords responses when trying to login.
