From: felix-php at 7val dot com
Operating system: Debian Linux
PHP version: 5.2.8
PHP Bug Type: DOM XML related
Bug description: segfault in dom_document_parser in recovery mode
Description:
------------
A call to DOMDocument::load() or ::loadXML() in recovery mode leads to
segmentation fault in dom_document_parser) when the XML declaration
contains an unknown (and unrecoverable) encoding.
The segfault occurs in document.c +1690 when trying to access properties
of the result document (ret), which is NULL in this case:
if (ret->URL == NULL && ctxt->directory != NULL) {
Reproduce code:
---------------
<?php
$xml = '<?xml version="1.0" encoding="bad"?>';
$dom = new DOMDocument;
$dom->recover = true;
$dom->loadXML($xml);
echo $dom->saveXML();
Expected result:
----------------
<?xml version="1.0"?>
Actual result:
--------------
Segmentation Fault
