Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP contains several vulnerabilities including a heap buffer overflow, |
| 19 |
potentially leading to the remote execution of arbitrary code under |
| 20 |
certain conditions. |
| 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 |

Description |
| 39 |
=========== |
| 40 |
|
| 41 |
Several vulnerabilities were found in PHP by the Hardened-PHP Project |
| 42 |
and other researchers. These vulnerabilities include a heap-based |
| 43 |
buffer overflow in htmlentities() and htmlspecialchars() if called with |
| 44 |
UTF-8 parameters, and an off-by-one error in str_ireplace(). Other |
| 45 |
vulnerabilities were also found in the PHP4 branch, including possible |
| 46 |
overflows, stack corruptions and a format string vulnerability in the |
| 47 |
*print() functions on 64 bit systems. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
Remote attackers might be able to exploit these issues in PHP |
| 53 |
applications making use of the affected functions, potentially |
| 54 |
resulting in the execution of arbitrary code, Denial of Service, |
| 55 |
execution of scripted contents in the context of the affected site, |
| 56 |
security bypass or information leak. |
| 57 |
|
| 58 |
Workaround |
| 59 |
========== |
| 60 |
|
| 61 |
There is no known workaround at this time. |
| 62 |
|
| 63 |
Resolution |
| 64 |
========== |
| 65 |
|
| 66 |
All PHP users should upgrade to the latest version: |
| 67 |
|
| 68 |
# emerge --sync |
| 69 |
# emerge --ask --oneshot --verbose "dev-lang/php" |
| 70 |
