Package: xalan
Version: 1.11-2
Severity: grave
Justification: causes non-serious data loss
due to system freeze.
On the following file, "xalan -xsl rec.xsl -in rec.xsl" makes the
whole system freeze with a lot of disk activity (swap?). Here I
could eventually interrupt it after several minutes, but this was
not easy as the mouse pointer was no longer moving. This is an
obvious DoS.

xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/" name="add">
<xsl:call-template name="add"/>
</xsl:template>
</xsl:stylesheet>
Note that xsltproc doesn't have this problem, as libxslt has infinite
template recursion detection (thanks to xsltMaxDepth).
