mahara - several vulnerabilities

Several vulnerabilities were discovered in mahara, an electronic portfolio,
weblog, and resume builder. The following Common Vulnerabilities and
Exposures project ids identify them:

• CVE-2010-1667
  Multiple pages performed insufficient input sanitising, making them
  vulnerable to cross-site scripting attacks.
• CVE-2010-1668
  Multiple forms lacked protection against cross-site request forgery
  attacks, therefore making them vulnerable.
• CVE-2010-1670
  Gregor Anzelj discovered that it was possible to accidentally
  configure an installation of mahara that allows access to another
  user’s account without a password.
• CVE-2010-2479
  Certain Internet Explorer-specific cross-site scripting
  vulnerabilities were discovered in HTML Purifier, of which a copy
  is included in the mahara package.

For the stable distribution (lenny), the problems have been fixed in
version 1.0.4-4+lenny6.

For the testing distribution (squeeze), the problems will be fixed soon.

For the unstable distribution (sid), the problems have been fixed in
version 1.2.5.

We recommend that you upgrade your mahara packages.
