It was not that simple to make these changes for core-updates, so I'm sending the patches for review.
For expat, I "re-fix" a bug that was fixed on master already. This bug-fix is actually reachable from the HEAD of core-updates, but for some reason doesn't exist at HEAD. According to MITRE the bug does affect all currently released versions of expat: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0718 I noticed a "left-over" patch for a bug that is apparently fixed in the version of expat on core-updates (2.1.1), so it is deleted: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1283 For libxslt, I update to the latest version and remove patches that are no longer needed. The timestamp issue was addressed upstream [0] and the bug has been fixed in this version. These patches were strangely no longer listed in 'gnu/local.mk'.
