All branches of freedesktop-sdk are vulnerable to https://gnutls.org/security-new.html#GNUTLS-SA-2020-06-03.
I see the last time we had a major GnuTLS vulnerability, CVE-2020-11501, the issue was fixed in master and 19.08 about a week later by @jjardon (but not in 18.08, which is supposedly still supported, but not really). This time it's been four weeks and not fixed yet, so time for a ping. I suggest aggressive upstream release monitoring for GnuTLS and OpenSSL.
- Upgrade to GnuTLS 3.6.14
GnuTLS version is 3.6.14
