Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP contains several vulnerabilities including buffer and integer |
| 19 |
overflows which could under certain conditions lead to the remote |
| 20 |
execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
PHP is a widely-used general-purpose scripting language that is |
| 26 |
especially suited for Web development and can be embedded into HTML. |
| 27 |
|
| 28 |
Affected packages |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
Several vulnerabilities were found in PHP, most of them during the |
| 41 |
Month Of PHP Bugs (MOPB) by Stefan Esser. The most severe of these |
| 42 |
vulnerabilities are integer overflows in wbmp.c from the GD library |
| 43 |
(CVE-2007-1001) and in the substr_compare() PHP 5 function |
| 44 |
(CVE-2007-1375). Ilia Alshanetsky also reported a buffer overflow in |
| 45 |
the make_http_soap_request() and in the user_filter_factory_create() |
| 46 |
functions (CVE-2007-2510, CVE-2007-2511), and Stanislav Malyshev |
| 47 |
discovered another buffer overflow in the bundled XMLRPC library |
| 48 |
(CVE-2007-1864). Additionally, the session_regenerate_id() and the |
| 49 |
array_user_key_compare() functions contain a double-free vulnerability |
| 50 |
(CVE-2007-1484, CVE-2007-1521). Finally, there exist implementation |
| 51 |
errors in the Zend engine, in the mb_parse_str(), the unserialize() and |
| 52 |
the mail() functions and other elements. |
| 53 |
|
| 54 |
Impact |
| 55 |
====== |
| 56 |
|
| 57 |
Remote attackers might be able to exploit these issues in PHP |
| 58 |
applications making use of the affected functions, potentially |
| 59 |
resulting in the execution of arbitrary code, Denial of Service, |
| 60 |
execution of scripted contents in the context of the affected site, |
| 61 |
security bypass or information leak. |
| 62 |
|
| 63 |
Workaround |
| 64 |
========== |
| 65 |
|
| 66 |
There is no known workaround at this time. |
| 67 |
|
| 68 |
Resolution |
| 69 |
========== |
| 70 |
|
| 71 |
All PHP 5 users should upgrade to the latest version: |
| 72 |
|
| 73 |
# emerge --sync |
| 74 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.2.2" |
| 75 |
|
| 76 |
All PHP 4 users should upgrade to the latest version: |
| 77 |
|
| 78 |
# emerge --sync |
| 79 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-4.4.7" |
| 80 |
