Description Mark J. Cox 2004-05-14 16:16:38 UTC 
iDEFENSE identified a vulnerability in the Opera web browser that
could allow remote attackers to create or truncate arbitrary files.
The KDE team has found that a similar vulnerability also exists
in KDE.

A flaw in the telnet URL handler can allow options to be passed to the
telnet program allowing file creation or overwriting. An attacker
could create a carefully crafted link such that when opened by a
victim it creates or overwrites a file with the victim's permissions. 

A workaround to this issue is to remove the file:
/usr/share/services/telnet.protocol

Red Hat Enterprise Linux 2.1 users who have applied any previous
kdelib erratum are not vulnerable to this issue, as our updates
shipped without a telnet.protocol file.

Embargoed until May17

Additionally a flaw was found in the mailto: handler; this could allow
attackers to pass --display arguments to kmail in order to take
control of the victims machine.  This issue does affect RHEL2.1
