Debian Security Advisory DSA-003-1 security@debian.org
http://www.debian.org/security/ Wichert Akkerman
December 1, 2000
------------------------------------------------------------------------


Package : joe
Problem type : symlink attack
Debian-specific: no

The security fix for joe released on November 22, 2000 had a problem:
it created the DEADJOE file securily but didn't write anything to it.
This has been fixed in version 2.8.15.2 .

This is the text from the previous advisory:

When joe (Joe's Own Editor) dies due to a signal instead of a normal
exit it saves a list of the files it is editing to a file called `DEADJOE'
in its current directory. Unfortunately this wasn't done safely which made
joe vulnerable to a symlink attack.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
