Description:

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.

The patch below addresses the issue:

Credit:

The Apache Portable Runtime project would like to thank Iveta Cesalova 
(Red Hat) for reporting this issue.
