Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP is vulnerable to an integer overflow potentially allowing the |
| 19 |
remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
PHP is a widely-used general-purpose scripting language that is |
| 25 |
especially suited for Web development and can be embedded into HTML. |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
A flaw in the PHP memory handling routines allows an unserialize() call |
| 40 |
to be executed on non-allocated memory due to a previous integer |
| 41 |
overflow. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could execute arbitrary code with the rights of the web |
| 47 |
server user or the user running a vulnerable PHP script. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All PHP 5.x users should upgrade to the latest version: |
| 58 |

# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.6-r6" |
| 61 |
|
| 62 |
All PHP 4.x users should upgrade to the latest version: |
