Description Wolfgang Frisch 2020-01-23 09:08:13 UTC 
CVE-2020-5221

In uftpd before 2.11, it is possible for an unauthenticated user to perform a
directory traversal attack using multiple different FTP commands and read and
write to arbitrary locations on the filesystem due to the lack of a well-written
chroot jail in compose_abspath(). This has been fixed in version 2.11
