Subject: [RHSA-2003:036-01] Updated mgetty packages available
---------------------------------------------------------------------
Red Hat Security Advisory
Synopsis: Updated mgetty packages available
Advisory ID: RHSA-2003:036-01
Issue date: 2003-04-08
Updated on: 2003-04-08
Product: Red Hat Linux
Keywords: mgetty spool permission
Cross references:
Obsoletes: RHSA-2001:050
CVE Names: CAN-2002-1391 CAN-2002-1392
---------------------------------------------------------------------
1. Topic:
Updated mgetty packages are now available for Red Hat Linux 7.1,
7.2, 7.3, and 8.0. These updates close a possible buffer overflow and a
permissions problem present in versions of mgetty prior to version 1.1.29.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
3. Problem description:
mgetty is a getty replacement for use with data and fax modems.
mgetty can be configured to run an external program to decide whether or
not to answer an incoming call based on Caller ID information. Unpatched
versions of mgetty prior to 1.1.29 would overflow an internal buffer if the
caller name reported by the modem was too long.
Additionally, the faxspool script supplied with versions of mgetty prior to
1.1.29 used a simple permissions scheme to allow or deny fax transmission
privileges. This scheme was easily circumvented because the spooling
directory used for outgoing faxes was world-writable.
All users of mgetty should upgrade to these errata packages, which
contain mgetty 1.1.30 and are not vulnerable to these issues.
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.
