Details

Updated fetchmail packages are available for Red Hat Linux 6.2, 7, 7.1,
7.2, 7.3, and 8.0 which close a remotely-exploitable vulnerability in
unpatched versions of fetchmail prior to 6.1.0.

Fetchmail is a remote mail retrieval and forwarding utility intended for
use over on-demand TCP/IP links such as SLIP and PPP connections. Two bugs
have been found in the header parsing code in versions of Fetchmail prior
to 6.1.0.

The first bug allows a remote attacker to crash Fetchmail by sending a
carefully crafted DNS packet. The second bug allows a remote attacker to
carefully craft an email in such a way that when it is parsed by Fetchmail
a heap overflow occurs, allowing remote arbitrary code execution.

Both of these bugs are only exploitable if Fetchmail is being used in
multidrop mode (using the "multiple-local-recipients" feature).

All users of Fetchmail are advised to upgrade to the errata packages
containing a backported fix which is not vulnerable to these issues.


Solution

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.
