Mandriva Linux Security Advisory MDKSA-2006:013
http://www.mandriva.com/security/
_______________________________________________________________________

Package : kolab-resource-handlers
Date : January 12, 2006
Affected: 2006.0
_______________________________________________________________________

Problem Description:

A problem exists in how the Kolab Server transports emails bigger than
8KB in size and if a dot (".") character exists in the wrong place. If
these conditions are met, kolabfilter will double this dot and a
modified email will be delivered, which could lead to broken clear-text
signatures or broken attachments.

The updated packages have been patched to correct these problems.
