Bug description:module php5-librdf causes libxslt's security module to fail
Description:
------------
I have been able to replicate under three environment running Ubuntu LTS
php5 (cli, cgi or mod_php), libxslt 1.1.26 and the php5 module and librdf0
and the php5 module.
With the above setup, any <xsl:import href="local/file.xsl" /> call will
fail with the error
XSLTProcessor::importStylesheet(): Local file read for
/path/to/local/file.xsl refused
Using XSLCache will result in a segfault and no errors.
Removing php5's librdf module fixes the issue.
Test script:
---------------
# a.php
<?php
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL|E_STRICT|E_NOTICE);
//phpinfo();
$doc = new DOMDocument();
$xsl = new XSLTProcessor();
$xsl_filename = __DIR__ . '/collection.xsl';
$xml_filename = __DIR__ . '/collection.xml';
$doc->load($xsl_filename);
$xsl->importStyleSheet($doc);
$doc->load($xml_filename);
echo $xsl->transformToXML($doc);
# collection.xml
<collection>
<cd>
<title>Fight for your mind</title>
<artist>Ben Harper</artist>
<year>1995</year>
</cd>
<cd>
<title>Electric Ladyland</title>
<artist>Jimi Hendrix</artist>
<year>1997</year>
</cd>
</collection>
# collection.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:import href="file:///var/www/pgadmin/temp/collection2.xsl" />
<xsl:param name="owner" select="'Nicolas Eliaszewicz'"/>
<xsl:output method="html" encoding="iso-8859-1" indent="no"/>
<xsl:template match="collection">
Hey! Welcome to <xsl:value-of select="$owner"/>'s sweet CD collection!
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="cd">
<h1><xsl:value-of select="title"/></h1>
<h2>by <xsl:value-of select="artist"/> - <xsl:value-of
select="year"/></h2>
<hr />
</xsl:template>
</xsl:stylesheet>
# collection2.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:param name="owner" select="'Nicolas Eliaszewicz'"/>
<xsl:output method="html" encoding="iso-8859-1" indent="no"/>
<xsl:template match="collection">
Hey! Welcome to <xsl:value-of select="$owner"/>'s sweet CD collection!
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="cd">
<h1><xsl:value-of select="title"/></h1>
<h2>by00 <xsl:value-of select="artist"/> - <xsl:value-of
select="year"/></h2>
<hr />
</xsl:template>
</xsl:stylesheet>
Expected result:
----------------
A parsed XSLT document with the imported stylesheets. And no errors ;)
Actual result:
--------------
