Subject: Fix typo in Danish translation of shortcuts page that caused expoentional regexp... 
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f2529edcab749d9007c6e5d28734554aa8a28d1b;p=ikiwiki.git

Fix typo in Danish translation of shortcuts page that caused expoentional regexp blowup.

Complex regular subexpression recursion limit (32766) exceeded at
/home/joey/src/ikiwiki/IkiWiki.pm line 1532.

This doesn't fix the blowup potential itself, it just fixes the typo. :)

A sample page that causes the blowup is attached below for future
reference. The first directive is not terminated. Contributing are the
additional quotes around the following directives, which mean that they can
each be processed as a parameter to the first directive, or as an
individual directive. In resolving this ambiguity, the regexp blows up.
Happily, perl contains the explosion , so I don't think there is an exploit
here.
