GLSA 200501-18: KDE FTP KIOslave: Command injection

http://security.gentoo.org/

Severity:	normal
Title:	KDE FTP KIOslave: Command injection
Date:	01/11/2005
Bugs:	#73759
ID:	200501-18

Synopsis

The FTP KIOslave contains a bug allowing users to execute arbitrary FTP commands.

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. KDE provided KIOslaves for many protocols in the kdelibs package, one of them being FTP. These are used by KDE applications such as Konqueror.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-base/kdelibs	< 3.3.2-r2	>= 3.3.2-r2	All supported architectures

Description

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.

Resolution

All kdelibs users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose kde-base/kdelibs
