Description

A bug in joe(1), a userfriendly text editor, was found by Christer Öberg of Wkit Security AB a few weeks ago. After starting joe(1) it tries to open its configuration file joerc in the current directory, the users home directory and some other locations. joe(1) doesn't check the ownership of joerc when trying the current directory. An attacker could place a malicious joerc file in a public writeable directory, like /tmp, to execute commands with the privilege of any user (including root), which runs joe while being in this directory.
