1. Summary:

Updated fetchmail packages that fix insecure configuration file creation is
now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Fetchmail is a remote mail retrieval and forwarding utility.

A bug was found in the way the fetchmailconf utility program writes
configuration files. The default behavior of fetchmailconf is to write a
configuration file which may be world readable for a short period of time.
This configuration file could provide passwords to a local malicious
attacker within the short window before fetchmailconf sets secure
permissions. The Common Vulnerabilities and Exposures project has assigned
the name CVE-2005-3088 to this issue.

Users of fetchmail are advised to upgrade to these updated packages, which
contain a backported patch which resolves this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
