New squid packages available

New squid packages are available that fix various vulnerabilities. Some of
these vulnerabilities could be used to perform a denial of service (DoS)
attack or allow remote users to execute code as the user squid.

Squid is a high-performance proxy caching server. Various security issues
have been found in Squid up to and including version 2.4.STABLE2. These were:

- a memory leak in the SNMP code
- a crash on specially-formatted data in FTP URL parsing
- HTCP would still be active, even if it was disabled in the config file

These errata pacakges contain Squid version 2.4.STABLE3, which is not
vulnerable to these issues. It is recommended that all users of Squid
update to the fixed packages.

Note: SNMP support is disabled in the
default configuration of these packages (it was previously enabled).
If you need SNMP support, edit your squid configuration and change
the 'snmp_port' option; the default port for SNMP enabled-squid is
3401.

Thanks go to Jouko Pynnonen for notifying us of the FTP vulnerability and
to the Squid team for providing patches.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CAN-2002-0067, CAN-2002-0068, CAN-2002-0069 to these issues.

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.
