8 May 2007

moin vulnerabilities

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

  • Ubuntu 7.04
  • Ubuntu 6.10
  • Ubuntu 6.06 LTS

Software Description

Details

A flaw was discovered in MoinMoin’s error reporting when using the AttachFile action. 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. (CVE-2007-2423)

Flaws were discovered in MoinMoin’s ACL handling for calendars and includes. Unauthorized users would be able to read pages that would otherwise be unavailable to them.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.04
