New squid packages available to fix FTP-based DoS

New squid packages are available that fix a potential DoS in Squid's FTP
handling code. It is recommened that squid users update to the fixed
packages.

The packages for Red Hat Linux 6.2 also fix the problem described in
RHSA-2001:097-04; it was later discovered that Red Hat Linux 6.2 is
vulnerable to the same problem in accelerator-only mode.

2001-10-22: Packages are now available for Red Hat Linux 7.2.

Certain FTP requests could cause the Squid daemon to abort, making it
unavailable for a period of seconds. If enough of these requests are sent
in a short period of time, the Squid daemon will not be restarted.

Thanks go to Vladimir Ivaschenko for bringing this to our attention, and
to Henrik Nordstrom and the Squid team for providing a fix.

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.
