  "statement" : "Red Hat Product Security has rated this issue as having a Low security impact, because the \"victim\" has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it.\nSince Red Hat Enterprise Linux 6, 7 are Out-of-Support-Scope for Low/Moderate flaws, the issue is not currently planned to be addressed in future updates for RHEL-6,7. Only Important and Critical severity flaws will be addressed at this time.\nFor additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/ and Red Hat Enterprise Linux Life Cycle & Updates Policy: https://access.redhat.com/support/policy/updates/errata/.\nHere PR:L because we need minimum user privilege to run vim application/service.\nand A:L because impacted components are partially available, no total loss after exploitation.",
