Hi,

We have an unpatched vulnerability in our current libxslt package, CVE-2015-7995 [1], which can result in a crash when parsing a specially crafted XML document [2]. A very small patch fixing the issue has been committed upstream [3] but there has not been a new release yet. I believe we should backport this patch, as there is no way to know if a new version is going to be released anytime soon.
