It has been discovered that in ProFTPd, an FTP server, an attacker on the same physical host as the server may be able to perform a symlink attack allowing to elevate privileges in some configurations.
For the stable distribution (squeeze), this problem has been fixed in version 1.3.3a-6squeeze6. For the testing distribution (wheezy), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 1.3.4a-3. We recommend that you upgrade your proftpd-dfsg packages.
ProFTPd is a powerful FTP daemon supporting hidden directories, virtual hosts, and per-directory '.ftpaccess' files.
