I am using Magento 1.7.0.2 and just applied this patch. There where two errors
patching file app/code/core/Mage/Core/Model/Email/Template/Filter.php
Hunk #1 FAILED at 166.
Hunk #2 succeeded at 177 (offset -10 lines).
1 out of 2 hunks FAILED -- saving rejects to file app/code/core/Mage/Core/Model/Email/Template/Filter.php.rej
and
can't find file to patch at input line 2293
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git app/code/core/Zend/Xml/Security.php app/code/core/Zend/Xml/Security.php
|index a3cdbc8..8b697b9 100644
|--- app/code/core/Zend/Xml/Security.php
|+++ app/code/core/Zend/Xml/Security.php
--------------------------
File to patch:
Skip this patch? [y]
The first one I can fix manually myself but the second is trying to access a file which doesn't even exist?
