Alpine: idn2-utils, multiple libidn2 packages: security update to 2.2.0-r0

high Tenable Self-Hosted Container Security Plugin ID 424058

Description

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

- GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when
converting A-labels to U-labels. This makes it possible in some circumstances for one domain to
impersonate another. By creating a malicious domain that matches a target domain except for the inclusion
of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label
and then back to an ASCII label), arbitrary domains can be impersonated. (CVE-2019-12290)
