Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated man package fixing GID security problems.
Advisory ID: RHSA-2001:072-14
Issue date: 2001-05-28
Updated on: 2001-09-06
Product: Red Hat Linux
Keywords: man setgid heap overflow path makewhatis root GID
Cross references:
Obsoletes: RHSA-2001:069
---------------------------------------------------------------------
1. Topic:
Updated man packages fixing a local GID man exploit and a
potential GID man to root exploit, as well as a problem with the
man paths of Red Hat Linux 5.x and 6.x.
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 - alpha, i386, ia64
3. Problem description:
Users could gain access to the GID man by overrunning a buffer in the
ultimate_source() function.
Users with GID man could get root access by creating man pages with
filenames containing escape characters.
Furthermore, the previous errata package hardcoded Red Hat Linux 7.x
man paths even on Red Hat Linux 5.x and 6.x.
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.
