Bug#989505: Multiple security issues (CVE-2021-31870, CVE-2021-31871, CVE-2021-31872, CVE-2021-31873)

Source: klibc
Version: 2.0.6-1
Severity: important
Tags: security

klibc version 2.0.9 fixed various security issues.  These are fixed in
unstable but not yet in buster.  They were triaged as no-dsa by the
security team, so they should be fixed in a stable update instead.
