freeFTPd.exe in freeFTPd through 1.0.11 allows remote attackers to bypass authentication via a crafted SFTP session, as demonstrated by an OpenSSH client with modified versions of ssh.c and sshconnect2.c.
Stack-based buffer overflow in freeFTPd before 1.0.9 with Logging enabled, allows remote attackers to cause a denial of service (application crash), and possibly execute arbitrary code, via a long USER command.
Multiple buffer overflows in freeFTPd 1.0.8, without logging enabled, allow remote authenticated attackers to cause a denial of service (application crash), and possibly execute arbitrary code, via long (1) MKD and (2) DELE commands.
