Version     : 0.13.5
Release     : 1.fc16
URL         : http://pediapress.com/code/
Summary     : MediaWiki parser and utility library
Description :
mwlib provides a library for parsing MediaWiki articles and converting them to
different output formats. mwlib is used by Wikipedia's "Print/export" feature
in order to generate PDF documents from Wikipedia articles.

--------------------------------------------------------------------------------
Update Information:

Update to version 0.13.5, which solves the following issues:

It was reported that mwlib suffered from a flaw that could allow a remote
attacker to perform a denial of service attack on a mwlib installation by
forcing it to parse a specially-crafted #iferror magic function. This issue has
been resolved in version 0.13.5.

syntaxhighlight nodes are supported properly in version 0.13.5.
