SECURITY: CVE-2021-35940 (cve.mitre.org)
Restore fix for CVE-2017-12613 which was missing in 1.7.x branch, though
was addressed in 1.6.x in 1.6.3 and later via r1807976.
The fix was merged back to 1.7.x in r1891198.
Since this was a regression in 1.7.0, a new CVE name has been assigned
to track this, CVE-2021-35940.
Thanks to Iveta Cesalova <icesalov redhat.com> for reporting this issue.
