apr: Security fix for CVE-2021-35940
An out-of-bounds array read in the apr_time_exp*() functions was fixed in the Apache Portable Runtime 1.6.3 release (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch, and hence version 1.7.0 regressed compared to 1.6.3 and is vulnerable to the same issue.

+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.
