drupal6 - several vulnerabilities

Several vulnerabilities have been found in drupal6, a fully-featured
content management framework. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2009-2372
  Gerhard Killesreiter discovered a flaw in the way user signatures are
  handled. It is possible for a user to inject arbitrary code via a
  crafted user signature. (SA-CORE-2009-007)
• CVE-2009-2373
  Mark Piper, Sven Herrmann and Brandon Knight discovered a cross-site
  scripting issue in the forum module, which could be exploited via the
  tid parameter. (SA-CORE-2009-007)
• CVE-2009-2374
  Sumit Datta discovered that certain drupal6 pages leak sensitive
  information such as user credentials. (SA-CORE-2009-007)

Several design flaws in the OpenID module have been fixed, which could
lead to cross-site request forgeries or privilege escalations. Also, the
file upload function does not process all extensions properly leading
to the possible execution of arbitrary code.
(SA-CORE-2009-008)
