Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP Toolkit does not quote parameters, allowing for PHP source code |
| 19 |
disclosure on Apache, and a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
PHP Toolkit is a utility to manage parallel installations of PHP within |
| 25 |
Gentoo. It is executed by the PHP ebuilds at setup. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 app-admin/php-toolkit < 1.0.1 >= 1.0.1 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Toni Arnold, David Sveningsson, Michal Bartoszkiewicz, and Joseph |
| 39 |
reported that php-select does not quote parameters passed to the "tr" |
| 40 |
command, which could convert the "-D PHP5" argument in the |
| 41 |
"APACHE2_OPTS" setting in the file /etc/conf.d/apache2 to lower case. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could entice a system administrator to run "emerge php" or |
| 47 |
call "php-select -t apache2 php5" directly in a directory containing a |
| 48 |
lower case single-character named file, which would prevent Apache from |
| 49 |
loading mod_php and thereby disclose PHP source code and cause a Denial |
| 50 |
of Service. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
Do not run "emerge" or "php-select" from a working directory which |
| 56 |
contains a lower case single-character named file. |
| 57 |
|
| 58 |
Resolution |
| 59 |
========== |
| 60 |
|
| 61 |
All PHP Toolkit users should upgrade to the latest version: |
| 62 |
|
| 63 |
# emerge --sync |
| 64 |
# emerge --ask --oneshot --verbose ">=app-admin/php-toolkit-1.0.1" |
| 65 |
|
