fetchmail -- fetchmailconf local password exposure

Description:

The fetchmail team reports:

The fetchmailconf program before and excluding version 1.49 opened the run control file, wrote the configuration to it, and only then changed the mode to 0600 (rw-------). Writing the file, which usually contains passwords, before making it unreadable to other users, can expose sensitive password information.
