* CVE-2016-4658: use-after-free error could lead to crash [bsc#1005544]
* Fix NULL dereference in xpointer.c when in recovery mode [bsc#1014873]
* CVE-2016-9597: An XML document with many opening tags could have caused
 a overflow of the stack not detected by the recursion limits, allowing
 for DoS (bsc#1017497).
For CVE-2016-9318 we decided not to ship a fix since it can break existing setups. Please take appropriate actions if you parse untrusted XML files and use the new -noxxe flag if possible (bnc#1010675, bnc#1013930).");
