[RHSA-2003:036-01] Updated mgetty packages available From: bugzilla@redhat.com To: redhat-watch-list@redhat.com, redhat-announce-list@redhat.com CC: bugtraq@securityfocus.com, full-disclosure@lists.netsys.com Date: 2003-04-08 14.17 --------------------------------------------------------------------- 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. 5.

Hi, From http://www.leo.org/~doering/mgetty/mgetty_5.html : "Before you can run `make install' to setup and install everything, make sure that the user that you specified for `FAX_OUT_USER' in `Makefile' exists in your system." Maybe this should be checked by the 1.1.30 ebuild? Because if this user does not exist, then emerge fails: make[1]: Entering directory `/var/tmp/portage/mgetty-1.1.30/work/mgetty-1.1.30/fax' for i in faxspool faxrunq faxq faxrm ; do \ mv -f /var/tmp/portage/mgetty-1.1.30/image//usr/bin/$i /var/tmp/portage/mgetty-1.1.30/image//usr/bin/$i.old 2>/dev/null ; \ install -c -o bin -g bin -m 755 $i /var/tmp/portage/mgetty-1.1.30/image//usr/bin ; \ done install -c -o bin -g bin -m 755 faxrunqd /var/tmp/portage/mgetty-1.1.30/image//usr/sbin install -c -o bin -g bin faxq-helper /var/tmp/portage/mgetty-1.1.30/image//usr/lib/mgetty+sendfax chown fax /var/tmp/portage/mgetty-1.1.30/image//usr/lib/mgetty+sendfax/faxq-helperchown: `fax': invalid user make[1]: *** [install] Error 1 make[1]: Leaving directory `/var/tmp/portage/mgetty-1.1.30/work/mgetty-1.1.30/fax'make: *** [install.bin] Error 2 It would be better if emerge could stop before compiling anything, with some info about the need to create a "fax" user. Thanks, -- Thomas.
glsa sent and fixed fax user problem.
