Hi,

The following vulnerability was published for ant.

CVE-2020-11979[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
