                  mailing list.

A security hole was discovered in the package mentioned above. Please update the package in your installation as soon as possible.


1. Problem Summary(From the Red Hat, Inc. Bug Fix Advisory)

The updated IMAP server released in errata advisory RHSA:102-04 exposes a bug in fetchmail's implementation of the AUTHENTICATE GSSAPI command.

2. Solution

Update the package from our ftp server by running the following command:

rpm -Uvh --nodeps --force ftp_path_to_filename

Where ftp_path_to_filename is the following:

ftp://ftp.turbolinux.com/pub/updates/6.0/security/fetchmail-5.5.0-3.i386.rpm

The source RPM can be downloaded here:

ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/fetchmail-5.5.0-3.src.rpm

**Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.

Please verify the MD5 checksums of the updates before you install:

  MD5 sum                               Package Name

These packages are GPG signed by Turbolinux for security. Our key is available here:

To verify a package, use the following command:

rpm --checksig name_of_rpm

To examine only the md5sum, use the following command:

rpm --checksig --nogpg name_of_rpm

**Note: Checking GPG keys requires RPM 3.0 or higher.
