Slackware Linux /usr/bin/ppp-off Symlink Vulnerability
In SlackWare Linux the script /usr/bin/ppp-off writes the output of 'ps x' to /tmp/grep.tmp. Since root is the user that runs ppp-off, a non-privileged user could create a link from /tmp/grep.tmp to any file(ie: /etc/issue), thus when root runs the ppp-off script, the output of 'ps x' would be put in the linked file.
Mitigation:
Ensure that the /usr/bin/ppp-off script is not writable by non-privileged users.
