Netwosix Linux Security Advisory #2004-0004  
- -----------------------------------------------------------------------------------

Package name:      libxml2
Summary:              Buffer overflow in the nanohttp or nanoftp  modules in 
XMLSoft Libxml2 2.6.0
Date:                    2004-03-04
Affected versions:  Netwosix 1.0
************************************************************************************

- -> Package description:
- ------------------------
Libxml2 is the XML C parser and toolkit developed for the Gnome project.

- -> Problem description:
- ------------------------
 A flaw in libxml2 versions prior to 2.6.6 was found by Yuuichi
 Teranishi.  When fetching a remote source via FTP or HTTP, libxml2
 uses special parsing routines that can overflow a buffer if passed a
 very long URL.  In the event that the attacker can find a program that
 uses libxml2 which parses remote resources and allows them to
 influence the URL, this flaw could be used to execute arbitrary code.

- -> Action:
- ------------------------
  We recommend that all systems with this package installed be upgraded.
  Please note that if you do not need the functionality provided by this

- -> About Linux Netwosix:
- ---------------------------------
Linux Netwosix is a powerful and optimized Linux distribution for servers
and Network Security related jobs.  It can also be used for special operations
such as penetration testing with its big collection of security oriented
software and sources. It's a light distribution created for the requirements
of every SysAdmin and it's very portable and highly configurable. Our
philosophy is to give greater liberty for  configuration to the SysAdmin.

systems but more flexible and usable.
