   An update that solves three vulnerabilities and has two
   fixes is now available.

Description:


   This update for libxml2 fixes the following issues:

   * 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).
