libxml2 - security update

Description

Nick Wellnhofer discovered that certain function calls inside XPath predicates can lead to use-after-free and double-free errors when executed by libxml2's XPath engine via an XSLT transformation. For the oldstable distribution (jessie), this problem has been fixed in version 2.9.1+dfsg1-5+deb8u6. For the stable distribution (stretch), this problem has been fixed in version 2.9.4+dfsg1-2.2+deb9u2. We recommend that you upgrade your libxml2 packages. For the detailed security status of libxml2 please refer to its security tracker page at: <https://security-tracker.debian.org/tracker/libxml2>
