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.

Credit:

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