Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP is affected by multiple issues, including a buffer overflow in |
| 19 |
wordwrap() which may lead to 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. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-lang/php < 5.1.4 >= 5.1.4 |
| 34 |
*>= 4.4.2-r2 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Several vulnerabilities were discovered on PHP4 and PHP5 by Infigo, |
| 40 |
Tonu Samuel and Maksymilian Arciemowicz. These included a buffer |
| 41 |
overflow in the wordwrap() function, restriction bypasses in the copy() |
| 42 |
and tempname() functions, a cross-site scripting issue in the phpinfo() |
| 43 |
function, a potential crash in the substr_compare() function and a |
| 44 |
memory leak in the non-binary-safe html_entity_decode() function. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
Remote attackers might be able to exploit these issues in PHP |
| 50 |
applications making use of the affected functions, potentially |
| 51 |
resulting in the execution of arbitrary code, Denial of Service, |
| 52 |
execution of scripted contents in the context of the affected site, |
| 53 |
security bypass or information leak. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this point. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All PHP users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.4" |
| 67 |
|
| 68 |
PHP4 users that wish to keep that version line should upgrade to the |
| 69 |
latest 4.x version: |
| 70 |
|
| 71 |
# emerge --sync |
| 72 |
# emerge --ask --oneshot --verbose =dev-lang/php-4.4.2-r2 |
| 73 |
|
| 74 |
