Proftpd

mod_sqlpw module in ProFTPD does not reset a cached password when a user uses the "user" command to change accounts, which allows authenticated attackers to gain privileges of other users.

mod_radius in ProFTPD before 1.3.7c allows memory disclosure to RADIUS servers because it copies blocks of 16 characters.

Integer overflow in kbdint.c in mod_sftp in ProFTPD 1.3.4d and 1.3.5r3 allows remote attackers to cause a denial of service (memory consumption) via a large response count value in an authentication request, which triggers a large memory allocation.

ProFTPD before 1.3.5rc1, when using the UserOwner directive, allows local users to modify the ownership of arbitrary files via a race condition and a symlink attack on the (1) MKD or (2) XMKD commands.

The pr_data_xfer function in ProFTPD before 1.3.2rc3 allows remote authenticated users to cause a denial of service (CPU consumption) via an ABOR command during a data transfer.

The mod_tls module in ProFTPD before 1.3.2b, and 1.3.3 before 1.3.3rc2, when the dNSNameRequired TLS option is enabled, does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 client certificate, which allows remote attackers…

postinst installation script for Proftpd in Debian 2.2 does not properly change the "run as uid/gid root" configuration when the user enables anonymous access, which causes the server to run at a higher privilege than intended.

ProFTPd 1.2 compiled with the mod_sqlpw module records user passwords in the wtmp log file, which allows local users to obtain the passwords and gain privileges by reading wtmp, e.g. via the last command.
