Title:
passlib failure to sanitize env variables PASSLIB_MAX_PASSWORD_SIZE
Status in OpenStack Identity (Keystone):
In Progress
Bug description:
Grant Murphy originally reported:
* Usage of passlib
The keystone server does not appear to sanitize the environment when
starting. This means that an unintended value can be set for
PASSLIB_MAX_PASSWORD_SIZE. Which will overwrite the default value of
4096 and potentially cause an unhandled passlib.exc.PasswordSizeError.
We should ensure sensible defaults are applied here prior to loading passlib.
If this is exploitable it will need a CVE, if not we should still
harden it so it can't be monkeyed with in the future.
