PARTIAL Summary
Zend/zend_hash.c in PHP before 7.0.15 and 7.1.x before 7.1.1 mishandles certain cases that require large array allocations, which allows remote attackers to execute arbitrary code or cause a denial of service (integer overflow, uninitialized memory access, and use of arbitrary destructor function pointers) via crafted serialized data.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Forced Integer Overflow This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

| description | Description: ------------ There was found a bug showing that PHP uses uninitialized memory during calls to `unserialize()`. As the following report shows, the payload supplied to `unserialize()` may control this uninitialized memory region and thus may be used to trick PHP into operating on faked objects and calling attacker controlled destructor function pointers. The supplied proof of concept exploit practically demonstrates the issue by executing arbitrary code solely by passing a specially crafted string to `unserialize()`. Even though this particular demo exploit only works locally this flaw is very likely to also allow for remote code execution. This bug was found using `afl-fuzz` / `afl-utils`. ### Analysis The following shows a short gdb dump of the flaw in a custom-built PHP (git master on 40727d7ce9) with debugging symbols ([1], [2]): $ gdb ./sapi/cli/php gdb> r test.php payload.master [...] Fatal error: Possible integer overflow in memory allocation (2736264714 * 32 + 32) in test.php on line 6 Program received signal SIGSEGV, Segmentation fault. gdb> i r rax 0x7ffff7fb673c 140737353836348 rbx 0x3030303030303030 3472328296227680304 rcx 0xf6d9 63193 rdx 0x1cb8c30 30116912 rsi 0x0 0 rdi 0x3030303030303030 3472328296227680304 rbp 0x30303030 0x30303030 rsp 0x7fffffffc080 0x7fffffffc080 r8 0x7ffff7fb6740 140737353836352 r9 0x1cb4d00 30100736 r10 0xeb 235 r11 0x206 518 r12 0x1c96ad8 29977304 r13 0x30303030 808464432 r14 0x7ffff167be00 140737243495936 r15 0x3030303030303030 3472328296227680304 << !!!

This allocation fails a bit later because of an integer overflow in the size parameter that is detected in `zend_hash_check_size()` called from `_zend_hash_init()`. As soon as this overflow is detected, PHP starts to shut down. At this point the contents of the partially initialized `zend_array` look as follows: gdb> c Fatal error: Possible integer overflow in memory allocation (2736264714 * 32 + 32) in test.php on line 6 Hardware access (read/write) watchpoint 2: *0x7ffff167be00 Value = 1 0x00000000010b6f6e in i_zval_ptr_dtor (zval_ptr=<optimized out>) at Zend/zend_variables.h:48 48 if (!--GC_REFCOUNT(ref)) { gdb> x/16x 0x00007ffff167be00 0x7ffff167be00: 0x00000001 0x00008007 0x00000012 0x30303030 0x7ffff167be10: 0x30303030 0x30303030 0x30303030 0x30303030 0x7ffff167be20: 0x30303030 0x30303030 0x30303030 0x30303030 0x7ffff167be30: 0x30303030 0x30303030 0xf167be70 0x00007fff During shutdown PHP attempts to destroy its internal objects as well as the corrupted array shown above. Therefore at some point the arrays own destructor gets called from `zend_hash_destroy()` which was overwritten with user supplied contents: ```c ZEND_API void ZEND_FASTCALL zend_hash_destroy(HashTable *ht) { // ... 1231 if (HT_IS_WITHOUT_HOLES(ht)) { 1232 do { 1233 ht->pDestructor(&p->val); 1234 } while (++p != end); 1235 } else { // ... ``` ### PoC The following PoC exploit was developed for PHP 7.0.14 shipped with the Archlinux (x64) distribution: $ uname -a Linux box01 4.8.13-1-ARCH #1 SMP PREEMPT Fri Dec 9 07:24:34 CET 2016 x86_64 GNU/Linux $ php --version PHP 7.0.14 (cli) (built: Dec 7 2016 17:11:27) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies For the PoC `exploit.py` ([3]) to work you'll need the PHP test script `test.php` ([1]) as well as the master payload file `payload.master` ([2]) to be placed in the same directory.
