Package        : typo3-src
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2009-0255 CVE-2009-0256 CVE-2009-0257 CVE-2009-0258
Debian Bug     : 512608
BugTraq ID     : 33376

Several remotely exploitable vulnerabilities have been discovered in the
TYPO3 web content management framework.  The Common Vulnerabilities and
Exposures project identifies the following problems:

   Chris John Riley discovered that the TYPO3-wide used encryption key is
   generated with an insufficiently random seed resulting in low entropy
   which makes it easier for attackers to crack this key.

   Marcus Krause discovered that TYPO3 is not invalidating a supplied session
   on authentication which allows an attacker to take over a victims
   session via a session fixation attack.

   Multiple cross-site scripting vulnerabilities allow remote attackers to
   inject arbitrary web script or HTML via various arguments and user-
   supplied strings used in the indexed search system extension, adodb
   extension test scripts or the workspace module.

   Mads Olesen discovered a remote command injection vulnerability in
   the indexed search system extension which allows attackers to
   execute arbitrary code via a crafted file name which is passed
   unescaped to various system tools that extract file content for
   the indexing.

Because of CVE-2009-0255, please make sure that besides installing
this update, you also create a new encryption key after the

For the stable distribution (etch) these problems have been fixed in
version 4.0.2+debian-7.

For the unstable distribution (sid) these problems have been fixed in
version 4.2.5-1.

We recommend that you upgrade your TYPO3 packages.

Upgrade instructions
- --------------------

wget url
       will fetch the file for you
dpkg -i file.deb
       will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
       will update the internal database
apt-get upgrade
       will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
