Debian: DSA-1711-1: New TYPO3 packages fix remote code execution
Summary
Several remotely exploitable vulnerabilities have been discovered in the
TYPO3 web content management framework. The Common Vulnerabilities and
Exposures project identifies the following problems:
CVE-2009-0255
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.
CVE-2009-0256
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.
CVE-2009-0257
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.
CVE-2009-0258
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
installation.
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.
