[A] Doesn't have security implications if roundup is correnctly 
configured. The bug would create a python backtrace. Unless the
"debug" option in section [web] is set (which is explicitly
discouraged) this will only display "an error has occurred" in the
web-interface. Even if someone sets the debug option in a
production release only the hashed password could be disclosed.
Note that this bug only affects the anydbm backend which should not
be used for a production version either.

How is the password hashed?

We're using PBKDF2 now for some time. The number of rounds can be
configured and currently defaults to 10000. Note that we encode the used
hashing function in the password field in the database. This allows us
to upgrade existing passwords on user login to the new scheme. This also
means existing installations can have a mixture of password hashing
schemes in the DB.

The old default scheme was SHA-1 with no salt, see

This was changed to PBKDF2 in Release 1.4.17 and there was still the bug
[A] remaining in the anydbm backend which was fixed in 1.4.20. This also
shows how many people are using that backend (it's mainly used for demo)
