Comment 8 Todd Cullum 2020-08-24 19:54:56 UTC 
Statement:

ark as shipped with Red Hat Enterprise Linux 7 prompts the user before allowing extraction into home directory, and also displays an error. Because the user must agree to perform the extraction in the home directory, Red Hat Product Security does not view this as a security vulnerability in ark as shipped with Red Hat Enterprise Linux 7.
Comment 9 Product Security DevOps Team 2020-08-24 21:15:15 UTC
