RHSA-2007:0344 - Security Advisory

Topic

Updated evolution-data-server package that fixes a security bug are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The evolution-data-server package provides a unified backend for programs
that work with contacts, tasks, and calendar information.

A flaw was found in the way evolution-data-server processed certain APOP
authentication requests. By sending certain responses when
evolution-data-server attempted to authenticate against an APOP server, a
remote attacker could potentially acquire certain portions of a user's
authentication credentials. (CVE-2007-1558)

All users of evolution-data-server should upgrade to these updated
packages, which contain a backported patch which resolves this issue.
