CVE-2011-0418
The glob implementation in Pure-FTPd before 1.0.32, and in libc in
NetBSD 5.1, does not properly expand expressions containing curly
brackets, which allows remote authenticated users to cause a denial of
service (memory consumption) via a crafted FTP STAT command.

CVE-2011-1575
The STARTTLS implementation in ftp_parser.c in Pure-FTPd before 1.0.30
does not properly restrict I/O buffering, which allows
man-in-the-middle attackers to insert commands into encrypted FTP
sessions by sending a cleartext command that is processed after TLS is
in place, related to a 'plaintext command injection' attack, a similar
issue to CVE-2011-0411.";

as announced in the referenced advisory.";

software upgrades.";
