SCA: security update for github.com/cloudflare/cfrpki (GHSA-3pqh-p72c-fj85)

medium Tenable Cloud Security Plugin ID 409635

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - When copying files with rsync, octorpki uses the "-a" flag 0, which forces rsync to copy binaries with the
 suid bit set as root. Since the provided service definition defaults to root (
 https://github.com/cloudflare/cfrpki/blob/master/package/octorpki.service ) this could allow for a vector,
 when combined with another vulnerability that causes octorpki to process a malicious TAL file, for a local
 privilege escalation. (CVE-2021-3978)
