Red Hat, Inc. Security Advisory
Synopsis: Updated usermode packages available
Advisory ID: RHSA-2000:075-08
Issue date: 2000-10-05
Updated on: 2000-11-27
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.
2000-11-27: Added packages for Red Hat Linux 7 for Alpha
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 7.0 - i386, alpha
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.
These updated packages also fix a problem due to an incorrect path
specification in the /usr/bin/shutdown wrapper script and close a
potential
security vulnerability in the userhelper binary.
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 19034 - shutdown
wrapper references non-existent /usr/sbin/shutdown 20160 - shutdown
script contains call to /usr/sbin/shutdown, which doesn't exist 20027
- /usr/sbin/userhelper dies in segmentation fault
