Summary
Updated ant packages fix security vulnerability:
As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions
of temporary files it created so that only the current user was allowed
to access them. Unfortunately the fixcrlf task deleted the temporary file
and created a new one without said protection, effectively nullifying the
effort. This would still allow an attacker to inject modified source files
into the build process(CVE-2020-11979).
