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
---------------------------------------------------------------------
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 - i386, alpha, sparc
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
Red Hat Linux 7.0 - i386
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
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):
N/A
