This is an out-of-bounds memory access in libxml2. By entering a unclosed
html comment such as <!-- the libxml2 parser didn't stop parsing at the end
of the buffer, causing random memory to be included in the parsed comment
that was returned to ruby. In Shopify, this caused ruby objects from
previous http requests to be disclosed in the rendered page.
