It was discovered that clean_html() function of lxml (pythonic bindings for the libxml2 and libxslt libraries) performed insufficient sanitisation for some non-printable characters. This could lead to cross-site scripting.

For the stable distribution (wheezy), this problem has been fixed in version 2.3.2-1+deb7u1. For the testing distribution (jessie), this problem has been fixed in version 3.3.5-1. For the unstable distribution (sid), this problem has been fixed in version 3.3.5-1. We recommend that you upgrade your lxml packages.
