Package        : libxml2
CVE ID         : CVE-2017-15412
Debian Bug     : 883790

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:
