Red Hat, Inc. Security Advisory
Synopsis: Updated usermode packages available
Advisory ID: RHSA-2000:075-05
Issue date: 2000-10-05
Updated on: 2000-10-09
Product: Red Hat Linux
Keywords: usermode format-string
Cross references: N/A
---------------------------------------------------------------------
1. Topic:
Updated usermode packages are now available for Red Hat Linux 6.x and
7.
2. Relevant releases/architectures:
Red Hat Linux 6.0 - i386, alpha, sparc
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 6.2EE - i386, alpha, sparc
Red Hat Linux 7.0 - i386
Red Hat Linux 7.0J - i386
3. Problem description:
The usermode package contains a binary (/usr/bin/userhelper), which
is used to control access to programs which are to be executed as
root. Because programs invoked by userhelper are not actually
running setuid-root, security measures built into recent versions of
glibc are not active.
If one of these programs supports internationalized text messages, a
malicious user can use the LANG or LC_ALL environment variables
(which are inherited by userhelper and, in turn, any programs it
runs) to create a format-string exploit in these programs.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
18046 - Another security hole in usermode/glibc

These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:
http://www.redhat.com/corp/contact.html
You can verify each package with the following command:
rpm --checksig <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>
