The uuxqt utility can be used to execute arbitrary commands as uucp.uucp

This is a re-release of a prior uucp exploit errata which also prevents
unique substrings being used with long options.

uuxqt, in the Taylor UUCP package, does not properly remove dangerous long
options. These long options allow local users to gain uid and gid uucp
privileges by calling uux and specifying an alternate configuration file
with the --config option.

Please note, Red Hat Linux 7.2 is vulnerable to this bug.

Additionally, Red Hat Linux 7.2 uses a different locking scheme than
prior versions and the 7.2 packages should not be applied to Red Hat
Linux 7.0 or 7.1 systems. Use the relevant packages from this errata
instead.

Conversely, the 7.1 packages from this errata should not be applied to
a Red Hat Linux 7.2 system.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0873 to this issue.

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.
