New squid packages for Red Hat Linux 7.0

New squid packages are available for Red Hat Linux 7.0 that fix a possible
security problem with Squid's HTTP accelerator feature. If Squid was
configured in accelerator-only mode, it was possible for remote users
to portscan machines through the Squid proxy, potentially allowing for
access to machines not otherwise available.

It is recommended that users who use Squid in accelerator-only mode update
to the fixed packages. Note that Red Hat Linux 7.1 is not affected by this
vulnerability, nor are releases prior to Red Hat Linux 7.0.

If Squid is configured with 'httpd_accel_host <some hostname>' and
'httpd_accel_with_proxy off', access control lists will not be enabled.
This could allow any remote user to use the squid server to access other
sites, potentially ones that they could not reach otherwise.

Thanks go to Paul Nasrat <pnasrat@uk.now.com> for notifying us of this
vulnerability and to the Squid team for providing the patch.

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.
