More information:

Felix Wilhelm discovered that libxml2, the GNOME XML library, did not correctly check for integer overflows or used wrong types for buffer sizes. This could result in out-of-bounds writes or other memory errors when working on large, multi-gigabyte buffers.

For Debian 9 stretch, this problem has been fixed in version 2.9.4+dfsg1-2.2+deb9u7.

We recommend that you upgrade your libxml2 packages.
