Hello Adam,

We have been monitoring the URL ftp://xmlsoft.org/libxml2/ for the latest release of the official patch of libxml2 containing the patches for the bugs associated with the CVE-2016-4658, CVE-2016-9318 and CVE-2016-9597, but have observed that no binary files have been released yet.

From the URL http://rpmfind.net/linux/RPM/opensuse/updates/leap/42.2/oss/src/libxml2-2.9.4-3.1.src.html we found that a RPM file has been released, but as our requirement is a binary version we can't go for the RPM version.

Could you kindly confirm the ETA for the release of the official libxml2 2.9.4-3.1 binary package containing all the above mentioned patches?

Kind regards,
Maumita Mandal
