16 `po4a-gettextize` uses more or less the same po4a features as our
17 `refreshpot` function.
19 Without specifying an input charset, zzuf'ed `po4a-gettextize` quickly
20 errors out, complaining it was not able to detect the input charset;
21 it leaves no incomplete file on disk. I therefore had to pretend the
22 input was in UTF-8, as does the po plugin.
24 zzuf -c -s 13 -r 0.1 \
25 po4a-gettextize -f text -o markdown -M utf-8 -L utf-8 \

32 Malformed UTF-8 character (fatal) at /usr/share/perl5/Locale/Po4a/Po.pm
35 An incomplete pot file is left on disk. Unfortunately Po.pm tells us
36 nothing about the place where the crash happens.

50 ### Blindly activating more po4a format modules
52 The format modules we want to use have to be checked, as not all are
53 safe (e.g. the LaTeX module's behaviour is changed by commands
54 included in the content); they may use regexps generated from
59 ## Hopefully non-holes
61 _(AKA, the assumptions that will be the root of most security holes...)_
65 No [documented](http://www.gnu.org/software/gettext/manual/gettext.html#PO-Files)
66 directive that can be put in po files is supposed to cause mischief
67 (ie, include other files, run commands, crash gettext, whatever).
73 The only past security issue I could find in GNU gettext is
74 [CVE-2004-0966](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0966),
75 *i.e.* [Debian bug #278283](http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=278283):
76 the autopoint and gettextize scripts in the GNU gettext package (1.14
77 and later versions) may allow local users to overwrite files via
78 a symlink attack on temporary files.
80 This plugin would not have allowed to exploit this bug, as it does not
81 use, either directly or indirectly, the faulty scripts.
83 Note: the lack of found security issues can either indicate that there
84 are none, or reveal that no-one ever bothered to find or publish them.
88 `refreshpofiles()` runs this external program.
90 * I was not able to crash it with `zzuf`.
91 * I could not find any past security hole.
95 `isvalidpo()` runs this external program.
97 * I was not able to make it behave badly using zzuf: it exits cleanly
98 when too many errors are detected.
99 * I could not find any past security hole.
103 #### Security history
105 The only past security issue I could find in po4a is
106 [CVE-2007-4462](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4462):
107 `lib/Locale/Po4a/Po.pm` in po4a before 0.32 allowed local users to
108 overwrite arbitrary files via a symlink attack on the
109 gettextization.failed.po temporary file.
111 This plugin would not have allowed to exploit this bug, as it does not
112 use, either directly or indirectly, the faulty `gettextize` function.
114 Note: the lack of found security issues can either indicate that there
115 are none, or reveal that no-one ever bothered to find or publish them.
119 Are there any security issues on running po4a on untrusted content?
121 To say the least, this issue is not well covered, at least publicly:
123 * the documentation does not talk about it;
124 * grep'ing the source code for `security` or `trust` gives no answer.
126 On the other hand, a po4a developer answered my questions in
127 a convincing manner, stating that processing untrusted content was not
128 an initial goal, and analysing in detail the possible issues.
129 The following analysis was done with his help.
133 * the core (`Po.pm`, `Transtractor.pm`) should be safe
134 * po4a source code was fully checked for other potential symlink
135 attacks, after discovery of one such issue
136 * the only external program run by the core is `diff`, in `Po.pm` (in
137 parts of its code we don't use)
138 * `Locale::gettext` is only used to display translated error messages
139 * Nicolas François "hopes" `DynaLoader` is safe, and has "no reason to
140 think that `Encode` is not safe"
141 * Nicolas François has "no reason to think that `Encode::Guess` is not
142 safe". The po plugin nevertheless avoids using it by defining the
143 input charset (`file_in_charset`) before asking `TransTractor` to
144 read any file. NB: this hack depends on po4a internals.
146 ##### Locale::Po4a::Text
148 * does not run any external program
149 * only `do_paragraph()` builds regexp's that expand untrusted
150 variables; according to [[Joey]], this is "Freaky code, but seems ok
151 due to use of `quotementa`".
155 `Text::WrapI18N` can cause DoS
156 ([Debian bug #470250](http://bugs.debian.org/470250)).
157 It is optional, and we do not need the features it provides.
159 If a recent enough po4a (>=0.35) is installed, this module's use is
160 fully disabled. Else, the wiki administrator is warned about this
165 `Term::ReadKey` is not a hard dependency in our case, *i.e.* po4a
166 works nicely without it. But the po4a Debian package recommends
167 `libterm-readkey-perl`, so it will probably be installed on most
168 systems using the po plugin.
170 `Term::ReadKey` has too far reaching implications for us to
171 be able to guarantee anything wrt. security.
173 If a recent enough po4a (>=2009-01-15 CVS, which will probably be
174 released as 0.35) is installed, this module's use is fully disabled.
178 ###### po4a-translate
180 * po4a CVS 2009-01-16
183 `po4a-translate` uses more or less the same po4a features as our
186 Without specifying an input charset, same behaviour as
187 `po4a-gettextize`, so let's specify UTF-8 as input charset as of now.
189 `LICENSES` is a 21M file containing 100 concatenated copies of all the
190 files in `/usr/share/common-licenses/`; I had no existing PO file or
191 translated versions at hand, which renders these tests
194 zzuf -cv -s 0:10 -r 0.001:0.3 \
195 po4a-translate -d -f text -o markdown -M utf-8 -L utf-8 \
196 -k 0 -m LICENSES -p LICENSES.fr.po -l test.fr
198 ... seems to lose the fight, at the `readpo(LICENSES.fr.po)` step,
199 against some kind of infinite loop, deadlock, or any similar beast.
201 The root of this bug lies in `Text::WrapI18N`, see the corresponding
212 # original contrib/po page, with old commentary
214 I've been working on a plugin called "po", that adds support for multi-lingual wikis,
215 translated with gettext, using [po4a](http://po4a.alioth.debian.org/).
219 * It can be found in my "po" branch:
220 `git clone git://gaffer.ptitcanardnoir.org/ikiwiki.git`
221 * It is self-contained, *i.e.* it does not modify ikiwiki core at all.
222 * It is documented (including TODO and plans for next work steps) in
223 `doc/plugins/po.mdwn`, which can be found in the same branch.
224 * No public demo site is available so far, I'm working on this.
226 My plan is to get this plugin clean enough to be included in ikiwiki.
228 The current version is a proof-of-concept, mature enough for me to dare submitting it here,
229 but I'm prepared to hear various helpful remarks, and to rewrite parts of it as needed.
231 Any thoughts on this?

546 The issue they were solving probably will arise again when I'll work
547 on my meta branch again (i.e. when the simplified po one is merged),
548 but the po thing is supposed to work without these ugly `our`.
549 Seems like it was the last unaddressed item from Joey's review, so I'm

651 * As discussed at [[todo/l10n]] the templates needs to be translatable too. They
652 should be treated properly by po4a using the markdown option - at least with my
653 later patches in [bug#530574](http://bugs.debian.org/530574)) applied.
655 * It seems to me that the po plugin (and possibly other parts of ikiwiki) wrongly
656 uses gettext. As I understand it, gettext (as used currently in ikiwiki) always
657 lookup a single language, That might make sense for a single-language site, but
658 multilingual sites should emit all strings targeted at the web output in each own
661 So generally the system language (used for e.g. compile warnings) should be separated
662 from both master language and slave languages.
664 Preferrably the gettext subroutine could be extended to pass locale as optional
665 secondary parameter overriding the default locale (for messages like "N/A" as
666 percentage in po plugin). Alternatively (with above mentioned template support)
667 all such strings could be externalized as templates that can then be localized.
671 ### Enabling/disabling the plugin
673 * enabling the plugin with `po_translatable_pages` set to blacklist: **OK**
674 * enabling the plugin with `po_translatable_pages` set to whitelist: **OK**
675 * enabling the plugin without `po_translatable_pages` set: **OK**
676 * disabling the plugin: **OK**
678 ### Changing the plugin config
680 * adding existing pages to `po_translatable_pages`: **OK**
681 * removing existing pages from `po_translatable_pages`: **OK**
682 * adding a language to `po_slave_languages`: **OK**
683 * removing a language from `po_slave_languages`: **OK**
684 * changing `po_master_language`: **OK**
685 * replacing `po_master_language` with a language previously part of
686 `po_slave_languages`: needs two rebuilds, but **OK** (this is quite
687 a perverse test actually)
689 ### Creating/deleting/renaming pages
691 All cases of master/slave page creation/deletion/rename, both via RCS
692 and via CGI, have been tested.
696 * general test with `usedirs` disabled: **OK**
697 * general test with `indexpages` enabled: **not OK**
698 * general test with `po_link_to=default` with `userdirs` enabled: **OK**
699 * general test with `po_link_to=default` with `userdirs` disabled: **OK**
