CVE-2017-12613

When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an
invalid month field value in Apache Portable Runtime APR 1.6.2 and prior,
out of bounds memory may be accessed in converting this value to an
apr_time_exp_t value, potentially revealing the contents of a different
static heap value or resulting in program termination, and may represent an
information disclosure or denial of service vulnerability to applications
which call these APR functions with unvalidated external input.
