A flaw was discovered in the FTP kioslave. KDE applications such as
Konqueror could be forced to execute arbitrary FTP commands via a
carefully crafted ftp URL. The URL could also be crafted in such a way
as to send an arbitrary email via SMTP. An attacker could make use of
this flaw if a victim clicks on a malcious link or visits a malicious
web site. The Common Vulnerabilities and Exposures project has
assigned the name CAN-2004-1165 to this issue.
This issue should also affect RHEL2.1
it's now fixed in kdelibs-2.2.2-15 and kdelibs-3.1.3-6.9.
