Bug description:Unserialize Invalid Date causes crash
Description:
------------
Core PHP,every version so far, 5.3.* and 5.4.*
When unserializing this string :
O:8:"DateTime":3:{s:4:"date";s:20:"10007-06-07
03:51:49";s:13:"timezone_type";i:3;s:8:"timezone";s:3:"UTC";}
created from: Datetime:createFromFormat("99-99-9999","j-n-Y");
then serialized, to a file. Later when read and working with, php crashes,
from
the parse_tz.c, in timelib_get_time_zone_info. the Exception is "read at
offset
0x00000010". it would appear that ts and / or tz is zero.
Test script:
---------------
$temp = unserialize('O:8:"DateTime":3:{s:4:"date";s:20:"10007-06-07
03:51:49";s:13:"timezone_type";i:3;s:8:"timezone";s:3:"UTC";}');
var_dump($temp);
Expected result:
----------------
error parsing invalid date or just a date with all entries 0.
Actual result:
--------------
php crash [read offset 0x00000010] ~ null pointer + offset. at the file
"ext\date\lib\parse_tz.c"
