Product: Red Hat Linux
Keywords: joe joerc cwd DEADJOE symlink vulnerability

1. Topic:
Updated joe packages are available for Red Hat Linux 5.2, 6.x and 7.
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
3. Problem description:
When starting, joe looks for a configuration file in the current working
directory, the user's home directory, and /etc/joe.
A malicious user could create a .joerc file in a world writable directory
such as /tmp and make users running joe inside that directory using a
.joerc file that is customized to execute commands with their own userids.
The current working directory has been removed from the list of possible
directories with the .joerc configuration file.
4. Solution:
To update all RPMs for your particular architecture, run:
rpm -Fvh
where 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 directly *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.
