Team, We are using lxml (lxml-3.3.4.win-amd64-py2.7) in my project which gets shipped with libxml2 2.9.0. We would like to upgrade libxml2 to 2.9.4 to mitigate security vulnerabilities (*CVE-2016-4448* ). For this upgrade we have to update lxml which has 2.9.4 libxml2. But latest lxml for 2.7 python 64 bit windows is having 2.9.3. Let me know how to solve the issue? Thanks. Python version used: python-2.7.12.amd64.msi
