Konqueror 3.3.1 allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline ("%0a") before the FTP command, which causes the commands to be inserted into the resulting FTP session, as demonstrated using a PORT command.

Albert Puigsech Galicia reports that Konqueror (more specifically kio_ftp) and Microsoft Internet Explorer are vulnerable to a FTP command injection vulnerability which can be exploited by tricking an user into clicking a specially crafted FTP URI.

It is also reported by Ian Gulliver and Emanuele Balla that this vulnerability can be used to tricking a client into sending out emails without user interaction.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:065 advisory.

  - security flaw (CVE-2004-1145, CVE-2004-1165)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A bug in the way kioslave handles URL-encoded newline (%0a) characters before the FTP command was discovered. Because of this, it is possible that a specially crafted URL could be used to execute any ftp command on a remote server, or even send unsolicited email.

As well, Davide Madrisan discovered that dcopidlng created temporary files in an insecure manner.

The updated packages are patched to deal with these issues.

The remote host is affected by the vulnerability described in GLSA-200501-18 (KDE FTP KIOslave: Command injection)

    The FTP KIOslave fails to properly parse URL-encoded newline     characters.
  Impact :

    An attacker could exploit this to execute arbitrary FTP commands on the     server and due to similiarities between the FTP and the SMTP protocol,     this vulnerability also allows an attacker to connect to a SMTP server     and issue arbitrary commands, for example sending an email.
  Workaround :

    There is no known workaround at this time.

Updated kdelib and kdebase packages that resolve several security issues are now available.

The kdelibs packages include libraries for the K Desktop Environment.
The kdebase packages include core applications for the K Desktop Environment.

Secunia Research discovered a window injection spoofing vulnerability affecting the Konqueror web browser. This issue could allow a malicious website to show arbitrary content in a different browser window. The Common Vulnerabilities and Exposures project has assigned the name CVE-2004-1158 to this issue.

A bug was discovered in the way kioslave handles URL-encoded newline (%0a) characters before the FTP command. It is possible that a specially crafted URL could be used to execute any ftp command on a remote server, or potentially send unsolicited email. The Common Vulnerabilities and Exposures project has assigned the name CVE-2004-1165 to this issue.

A bug was discovered that can crash KDE screensaver under certain local circumstances. This could allow an attacker with physical access to the workstation to take over a locked desktop session. Please note that this issue only affects Red Hat Enterprise Linux 2.1. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-0078 to this issue.

All users of KDE are advised to upgrade to this updated packages, which contain backported patches to correct these issues.

The remote host is using a version of Konqueror that is prone to a security flaw that may allow a malicious website to influence a pop up window from a trusted site.
An attacker may exploit this flaw to impersonate third-party web servers and convince a victim on the remote host into revealing personal information. 

Thiago Macieira discovered a vulnerability in the kioslave library, which is part of kdelibs, which allows a remote attacker to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline before the FTP command.

A vulnerability in the Konqueror web browser was discovered that would allow a malicious web site to take advantage of a flaw in kio_ftp to send email messages without user interaction.

The updated packages are patched to correct the problem.
