-----BEGIN PGP SIGNED MESSAGE-----Hash: SHA1KDE Security Advisory: ftp kioslave command injectionOriginal Release Date: 2005-01-01URL:http://www.kde.org/info/security/advisory-20050101-1.txt0. Referenceshttp://www.securityfocus.com/bid/11827http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-11651. Systems affected: All KDE releases up to including KDE 3.3.2.2. Overview: 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 similiarities 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.3. Impact: The FTP kioslave can be misused to execute any ftp command on the server or be a vector for sending out unsolicited email.4. Solution: Source code patches have been made available which fix these vulnerabilities. Contact your OS vendor / binary package provider for information about how to obtain updated binary packages.5. Patch: Patch for KDE 3.2.3 is available fromftp://ftp.kde.org/pub/kde/security_patches : a639b7b592f005e911c454a0a8c9c542 post-3.2.3-kdelibs-kioslave.patch Patch for KDE 3.3.2 is available fromftp://ftp.kde.org/pub/kde/security_patches : fe67157b26a8cdf5bcfa1898cdf3b154 post-3.3.2-kdelibs-kioslave.patch6.
