Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated minicom packages available
Advisory ID: RHSA-2001:067-03
Issue date: 2001-05-03
Updated on: 2001-05-09
Product: Red Hat Linux
Keywords: minicom security format string exploit

---------------------------------------------------------------------
1. Topic:
The minicom program allows any user with local shell access to obtain
group uucp priveledges. It may also be possible for the malicious
user to obtain root priveledges as well.
2. Relevant releases/architectures:
Red Hat Linux 5.2 - alpha, i386, sparc
Red Hat Linux 6.2 - alpha, i386, sparc
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - i386
3. Problem description:
Minicom contains a great number of format string abuses in it's usage
of several printf-like varargs functions. The program was never
written with security in mind, and as such even though many format
strings bugs have been fixed in this release, there are many more
lurking in the code.
This release solves the security problem by disabling setgid uucp on
the minicom binary.
4. 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
