Debian Security Advisory DSA 634-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
January 11th, 2005 http://www.debian.org/security/faq


Package : hylafax
Vulnerability : weak hostname and username validation
Problem-Type : local/remote
Debian-specific: no
CVE ID : CAN-2004-1182

Patrice Fournier discovered a vulnerability in the authorisation subsystem of hylafax, a flexible client/server fax system. A local or remote user guessing the contents of the hosts.hfaxd database could gain unauthorised access to the fax system.

Some installations of hylafax may actually utilise the weak hostname and username validation for authorized uses. For example, hosts.hfaxd entries that may be common are

192.168.0
username:uid:pass:adminpass
user@host

After updating, these entries will need to be modified in order to continue to function. Respectively, the correct entries should be

192.168.0.[0-9]+
username@:uid:pass:adminpass
user@host

Unless such maching of "username" with "otherusername" and "host" with "hostname" is desired, the proper form of these entries should include the delimiter and markers like this

@192.168.0.[0-9]+$
^username@:uid:pass:adminpass
^user@host$

For the stable distribution (woody) this problem has been fixed in version 4.1.1-3.1.

For the unstable distribution (sid) this problem has been fixed in version 4.2.1-1.

We recommend that you upgrade your hylafax packages.

Package : bmv
Vulnerability : insecure temporary file
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2003-0014

Peter Samuelson, upstream maintainer of bmv, a PostScript viewer for SVGAlib, discovered that temporary files are created in an insecure fashion. A malicious local user could cause arbitrary files to be overwritten by a symlink attack.

For the stable distribution (woody) this problem has been fixed in version 1.2-14.2.

For the unstable distribution (sid) this problem has been fixed in version 1.2-17.

We recommend that you upgrade your bmv packages.

Gentoo Linux Security Advisory GLSA 200501-18

http://security.gentoo.org/


Severity: Normal
Title: KDE FTP KIOslave: Command injection
Date: January 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


1 kde-base/kdelibs < 3.3.2-r2 >= 3.3.2-r2 *>= 3.2.3-r5

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

Note: There is currently no fixed stable 3.3.x version for sparc.

Gentoo Linux Security Advisory GLSA 200501-16

http://security.gentoo.org/


Severity: Normal
Title: Konqueror: Java sandbox vulnerabilities
Date: January 11, 2005
Bugs: #72750
ID: 200501-16


Synopsis

The Java sandbox environment in Konqueror can be bypassed to access arbitrary packages, allowing untrusted Java applets to perform unrestricted actions on the host system.

Background

KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. Konqueror is the KDE web browser and file manager.

Affected packages


     Package           /  Vulnerable  /                     Unaffected

  1  kde-base/kdelibs       < 3.3.2                           >= 3.3.2

Description

Konqueror contains two errors that allow JavaScript scripts and Java applets to have access to restricted Java classes.

Impact

A remote attacker could embed a malicious Java applet in a web page and entice a victim to view it. This applet can then bypass security restrictions and execute any command, or access any file with the rights of the user running Konqueror.

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

Note: There is currently no fixed stable version for sparc.

Gentoo Linux Security Advisory GLSA 200501-17

http://security.gentoo.org/


Severity: Normal
Title: KPdf, KOffice: More vulnerabilities in included Xpdf
Date: January 11, 2005
Bugs: #75203, #75204
ID: 200501-17


Synopsis

KPdf and KOffice both include vulnerable Xpdf code to handle PDF files, making them vulnerable to the execution of arbitrary code if a user is enticed to view a malicious PDF file.

Background

KPdf is a KDE-based PDF viewer included in the kdegraphics package. KOffice is an integrated office suite for KDE.

Affected packages


     Package               /  Vulnerable  /                 Unaffected


1 app-office/koffice < 1.3.5-r1 >= 1.3.5-r1 2 kde-base/kdegraphics < 3.3.2-r1 >= 3.3.2-r1 *>= 3.2.3-r3 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures.

Description

KPdf and KOffice both include Xpdf code to handle PDF files. Xpdf is vulnerable to multiple new integer overflows, as described in GLSA 200412-24.

Impact

An attacker could entice a user to open a specially-crafted PDF file, potentially resulting in the execution of arbitrary code with the rights of the user running the affected utility.

Workaround

There is no known workaround at this time.

Resolution

All KPdf users should upgrade to the latest version of kdegraphics:

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

Note: There is currently no fixed stable 3.3.x version for sparc.

All KOffice users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose app-office/koffice
