freeFTPd 1.0.8 has a Post-Authentication Buffer Overflow via a crafted SIZE command (this is exploitable even if logging is disabled).

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 (1) WeOnlyDo wodSSHServer ActiveX Component 1.2.7 and 1.3.3 DEMO, as used in other products including (2) FreeSSHd 1.0.9 and (3) freeFTPd 1.0.10, allows remote attackers to execute arbitrary code via a long key exchange algorithm string.

freeFTPd 1.0.10 allows remote authenticated users to cause a denial of service (null dereference and crash) via a PORT command with missing arguments.

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.
