An update that fixes one vulnerability is now available.

Description:

This update for uftpd fixes the following issues:

Changes:

* Use common log message format and log level when user enters an invalid
path. This unfortunately affects changes introduced in v2.11 to increase
logging at default log level.

CWD, a NULL ptr was deref. in a DBG() message even though the log level

could be permanent. (boo#1172959)
