KDE Security Advisory: KDE applications which use the ftp kioslave, e.g. Konqueror, allow remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains an URL-encoded newline ( %0a ) before the ftp command, which causes the commands to be inserted into the resulting FTP session. Due to similarities between the ftp and the SMTP protocol, this vulnerability allows to misuse the ftp slave to connect to a SMTP server and issue arbitrary commands, like sending an email. Systems affected: All KDE releases up to including KDE 3.3.2.
