Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP contains a function that, when used, could allow a remote attacker |
| 19 |
to execute 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. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-lang/php < 5.1.4-r6 *>= 4.4.3-r1 |
| 34 |
>= 5.1.4-r6 |
| 35 |
|
| 36 |
Description |
| 37 |
=========== |
| 38 |
|
| 39 |
The sscanf() PHP function contains an array boundary error that can be |
| 40 |
exploited to dereference a null pointer. This can possibly allow the |
| 41 |
bypass of the safe mode protection by executing arbitrary code. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker might be able to exploit this vulnerability in PHP |
| 47 |
applications making use of the sscanf() function, potentially resulting |
| 48 |
in the execution of arbitrary code or the execution of scripted |
| 49 |
contents in the context of the affected site. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All PHP 4.x users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-4.4.3-r1" |
| 63 |
|
| 64 |
All PHP 5.x users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.4-r6" |
| 68 |
