Bug description:certificates validity parsing does not work past 2050
Description:
------------
In asn1_time_to_time_t [ext/openssl/openssl.c], the Y2K bug makes a cameo
appearance:
[...]
*thestr = '\0';
thestr -= 2;
thetime.tm_year = atoi(thestr);
if (thetime.tm_year < 68) {
thetime.tm_year += 100;
}
This piece of code is the part of a backwards UTCTime parser. It moves 2
positions to the left, and converts those two characters to an int.
However, certs with a validity past 2050 contain GeneralizedTime formatted
timestamps allowing 4 characters in the year field instead of the UTCTime
this
function parses (badly). [rfc5280, 4.1.2.5]
Test script:
---------------
An example script that demonstrates the problem with a cert expiring 2101:

Expected result:
----------------
Actual time string of validity: 21010828070405Z
parsed with strtotime: 4154655845 [2101-08-28]
parsed with asn1_time_to_time_t: 4154655845 [2101-08-28]
Actual result:
--------------
Actual time string of validity: 21010828070405Z
parsed with strtotime: 4154655845 [2101-08-28]
parsed with asn1_time_to_time_t: 998982245 [2001-08-28]
