ecma/kjs_html.cpp in KDE JavaScript (KJS), as used in Konqueror in KDE 3.5.5, allows remote attackers to cause a denial of service (crash) by accessing the content of an iframe with an ftp:// URI in the src attribute, probably due to a NULL pointer dereference.

From Red Hat Security Advisory 2007:0909 :

Updated kdelibs packages that resolve several security flaws are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The kdelibs package provides libraries for the K Desktop Environment (KDE).

Two cross-site-scripting flaws were found in the way Konqueror processes certain HTML content. This could result in a malicious attacker presenting misleading content to an unsuspecting user.
(CVE-2007-0242, CVE-2007-0537)

A flaw was found in KDE JavaScript implementation. A web page containing malicious JavaScript code could cause Konqueror to crash.
(CVE-2007-1308)

A flaw was found in the way Konqueror handled certain FTP PASV commands. A malicious FTP server could use this flaw to perform a rudimentary port-scan of machines behind a user's firewall.
(CVE-2007-1564)

Two Konqueror address spoofing flaws have been discovered. It was possible for a malicious website to cause the Konqueror address bar to display information which could trick a user into believing they are at a different website than they actually are. (CVE-2007-3820, CVE-2007-4224)

Users of KDE should upgrade to these updated packages, which contain backported patches to correct these issues.

It was discovered that Konqueror did not correctly handle iframes from JavaScript. If a user were tricked into visiting a malicious website, Konqueror could crash, resulting in a denial of service.
(CVE-2007-1308)

A flaw was discovered in how Konqueror handled PASV FTP responses. If a user were tricked into visiting a malicious FTP server, a remote attacker could perform a port-scan of machines within the user's network, leading to private information disclosure. (CVE-2007-1564).
