- Can any sort of directives be put in po files that will
cause mischief (ie, include other files, run commands, crash gettext,
- whatever).
+ whatever). The [PO file
+ format](http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files)
+ should contain the answer.
- Any security issues on running po4a on untrusted content?

+- [CVE-2004-0966](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0966)
+ / [Debian bug #278283](http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=278283):
+ the autopoint and gettextize scripts in the GNU gettext package
+ 1.14 and later versions, as used in Trustix Secure Linux 1.5
+ through 2.1 and other operating systems, allows local users to

be fixed by something like [[todo/using_meta_titles_for_parentlinks]].
-### backlinks

-#### `po_link_to = negotiated`
-
-If a given translatable `sourcepage.mdwn` links to \[[destpage]],
-`sourcepage.LL.po` also link to \[[destpage]], and the latter has the
-master page *and* all its translations listed in the backlinks. On the
-other hand, translations of `destpage` get none of these backlinks.
-What would be nice is:
-
-- if a translatable page links to another translatable page: the
- master destpage gets a backlink to the master sourcepage, and every
- slave destpage gets a backlink to the corresponding slave sourcepage
-- if a translatable page links to a non-translatable page: the
- destpage gets a backlink to the master sourcepage only
-- if a non-translatable page links to a translatable page: every
- master or slave destpage gets a backlink to the sourcepage
-- if a non-translatable page links to another non-translatable page:
- the default behavious is nice, don't change it
-
-#### `po_link_to = current`

-At first glance, backlinks seem to work nicely, but a more thorough
-look is needed.
