Sets the patched version to 5.2.7 and adds the fix commit 8b7c6792 ("IZPACK-1820 Adds path traversal checks" (5.2 branch backport)). The commit is contained in the tag 5.2.7 and not in the previous release 5.2.6 (git tag --contains). 5.2.7 adds validateTargetPath() in UnpackerBase.unpack(), which rejects ".." segments; 5.2.6 has no check.
