Paul King updated GROOVY-9788:
------------------------------
Description:
{quote}
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.

[1] [CVE
Reference|https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-11979]
[2] [Apache Ant Security Reports|https://ant.apache.org/security.html]
Overall risk assessment for Groovy: *low*
Details:
* Groovy's internal usage of Ant is not affected by the above mentioned CVE.
* We encourage Groovy users using Groovy in combination with Ant, e.g.
{{AntBuilder}} to read the Apache Ant Security Report[1] and follow the
mitigation advice. In particular, anyone using the {{fixcrlf}} Ant task should
take note.
* Recent Groovy versions, e.g. 3.0.6, have been built against Ant 1.10.8 but do
not require that version and can safely be used with Ant 1.10.9 which has
additional protections against the vulnerability mentioned in the CVE.
