Ubuntu Security Notice USN-423-1

20th February, 2007

moin, moin1.3 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 6.10
  • Ubuntu 6.06 LTS
  • Ubuntu 5.10


A flaw was discovered in MoinMoin's debug reporting sanitizer which
could lead to a cross-site scripting attack. By tricking a user into
viewing a crafted MoinMoin URL, an attacker could execute arbitrary
JavaScript as the current MoinMoin user, possibly exposing the user's
authentication information for the domain where MoinMoin was hosted.
Only Ubuntu Breezy was vulnerable. (CVE-2007-0901)

An information leak was discovered in MoinMoin's debug reporting, which
could expose information about the versions of software running on the
host system. MoinMoin administrators can add "show_traceback=0" to
their site configurations to disable debug tracebacks. (CVE-2007-0902)
