CVE-2020-11979 · cross-distro fix matrix

CVE-2020-11979: 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

Affects 8 Linux releases across 13 (distro × package) combinations.
