| 63 | - CVE-2016-9935 (denial of service) |
| 64 | |
| 65 | The php_wddx_push_element function in ext/wddx/wddx.c in PHP before |
| 66 | 5.6.29 and 7.x before 7.0.14 allows remote attackers to cause a denial |
| 67 | of service (out-of-bounds read and memory corruption) or possibly have |
| 68 | unspecified other impact via an empty boolean element in a wddxPacket |
| 69 | XML document. |
| 70 | |
| 71 | - CVE-2016-9936 (arbitrary code execution) |
| 72 | |
| 73 | The unserialize implementation in ext/standard/var.c in PHP 7.x before |
| 74 | 7.0.14 allows remote attackers to cause a denial of service (use-after- |
| 75 | free) or possibly execute arbitrary code via crafted serialized data. |
| 76 | |
| 77 | - CVE-2017-5340 (arbitrary code execution) |
| 78 | |
| 79 | It was found that PHP uses uninitialized memory during calls to |
| 80 | `unserialize()`. The payload supplied to `unserialize()` may control |
| 81 | this uninitialized memory region and thus may be used to trick PHP into |
| 82 | operating on faked objects and calling attacker controlled destructor |
| 83 | function pointers, effectively allowing arbitrary code execution via |
| 84 | specially crafted serialized data. |
| 85 | |
| 86 | Impact |
| 87 | ====== |
| 88 | |
| 89 | A remote attacker is able to use specially crafted input to perform a |
| 90 | denial of service attack or execute arbitrary code on the affected |
| 91 | host. |
