Red Hat Linux 7.0 RHSA-2001:097-04 Critical: Squid ACL Bypass Issue

Calendar Grey July 19, 2001
Dist Redhat Esm H88
Recent squid updates for Red Hat Linux 7.0 resolve a significant security flaw related to an ACL circumvention, potentially enabling unauthorized access for unprivileged users.
New squid packages are available for Red Hat Linux 7.0 that fix a possible security problem with Squid's HTTP accelerator feature.

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.
