Hello, I noticed that CVE-2019-12522 [*] was not yet fixed. I could confirm the saved UID is indeed 0 (root) on a Ubuntu 20.04.1 machine (5.4 kernel) so I was wondering if a fix was on the way. Thanks Regards, Simon *: https://gitlab.com/jeriko.one/security/-/blob/master/squid/CVEs/CVE-2019-12522.txt
