Red Hat, Inc. Security Advisory Synopsis: Updated joe packages are available for Red Hat Linux 5.2, 6.x and 7 Advisory ID: RHSA-2000:110-06 Issue date: 2000-11-17 Updated on: 2000-11-20 Product: Red Hat Linux Keywords: joe DEADJOE symlink vulnerability Cross references: N/A
Updated joe packages are available for Red Hat Linux 5.2, 6.x and 7.
2. Relevant releases/architectures:
Red Hat Linux 5.2 - i386, alpha, sparc
3. Problem description:
When exiting joe in a nonstandard way (such as a system crash, closing an xterm, or a network connection going down), joe will unconditionally append its open buffers to the file "DEADJOE". This could be exploited by the creation of DEADJOE symlinks in directories where root would normally use joe. In this way, joe could be used to append garbage to potentially-sensitive files, resulting in a denial of service.
Users of Red Hat Linux 6.x and 5.2 should also note that joe's configuration files have been moved from /usr/lib/joe to /etc/joe
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):
6. RPMs required:

Red Hat Linux 6.0:
Red Hat Linux 6.1:
Red Hat Linux 6.2:
