Updated fetchmail packages available

Updated fetchmail packages are available for Red Hat Linux 6.2, 7, 7.1,
7.2, and 7.3 which close a remotely-exploitable vulnerability in unpatched
versions of fetchmail prior to 5.9.10.

When retrieving mail from an IMAP server, the fetchmail e-mail client will
allocate an array to store the sizes of the messages which
it will attempt to fetch. The size of the array is determined by the
number of messages that the server claims to have. Unpatched versions of
fetchmail prior to 5.9.10 did not check whether the number of e-mails the
server claimed was too high, allowing a malicious server to cause the
fetchmail process to write data outside of the array bounds.

Users of fetchmail are advised to upgrade to this errata package which is
not vulnerable to this issue.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0146 to this issue.

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. 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.
