Christer Öberg of Wkit Security AB found a problem in joe (Joe's Own Editor). joe will look for a configuration file in three locations: the current directory, the users homedirectory ($HOME) and in /etc/joe. Since the configuration file can define commands joe will run (for example to check spelling) reading it from the current directory can be dangerous: an attacker can leave a .joerc file in a writable directory, which would be read when a unsuspecting user starts joe in that directory.

Package        : joe
Problem type   : local exploit
Debian-specific: no

Christer Öberg of Wkit Security AB found a problem in joe (Joe's
Own Editor). joe will look for a configuration file in three
locations: the current directory, the users homedirectory ($HOME)
and in /etc/joe. Since the configuration file can define commands
joe will run (for example to check spelling) reading it from
the current directory can be dangerous: an attacker can leave
a .joerc file in a writable directory, which would be read when
a unsuspecting user starts joe in that directory.

This has been fixed in version 2.8-15.3 and we recommend that
you upgrade your joe package immediately.

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