COMMAND

    sysinstall

SYSTEMS AFFECTED

    FreeBSD prior to v3.0

PROBLEM

    Jonas  Eriksson  posted  following.   There  was  an  symlink race
    problem  in  FreeBSD  /stand/sysinstall  until FreeBSD version 3.0
    When root is reading  help-documents in sysinstall it  will create
    an tmp  file named  doc.tmp in  /tmp that  anyone could symlink to
    /etc/passwd for example.

SOLUTION

    FreeBSD 3.0 fixed this.
