Package        : typo3-src
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2010-3714 CVE-2010-3715 CVE-2010-3716 CVE-2010-3717

Several remote vulnerabilities have been discovered in TYPO3.  The
Common Vulnerabilities and Exposures project identifies the following
problems:

CVE-2010-3714
  Multiple remote file disclosure vulnerabilities in the jumpUrl
  mechanism and the Extension Manager allowed attackers to read
  files with the privileges of the account under which the web
  server was running.

CVE-2010-3715
  The TYPO3 backend contained several cross-site scripting
  vulnerabilities, and the RemoveXSS function did not filter
  all Javascript code.

CVE-2010-3716
  Malicious editors with user creation permission could escalate
  their privileges by creating new users in arbitrary groups, due
  to lack of input validation in the taskcenter.
  
CVE-2010-3717
  TYPO3 exposed a crasher bug in the PHP filter_var function,
  enabling attackers to cause the web server process to crash
  and thus consume additional system resources.
  
For the stable distribution (lenny), these problems have been fixed in
version 4.2.5-1+lenny6.

For the unstable distribution (sid) and the upcoming stable
distribution (squeeze), these problems have been fixed in version
4.3.7-1.

We recommend that you upgrade your TYPO3 packages.
