PHP5 before 5.4.4 allows passing invalid utf-8 strings via the
xmlTextWriterWriteAttribute, which are then misparsed by libxml2. This
results in memory leak into the resulting output.

| jdstrand | per Debian, This was initially reported to be a bug in libxml2, but it later showed that PHP |
| mdeslaur | can’t reproduce on quantal+ The reproducer only displays garbage if the suhosin patch is applied, which is why it doesn’t appear to work on quantal+ Need to check if libxml2 still walks past the end of the string if the suhosin patch isn’t applied. we will not be fixing this issue |
