Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PHP suffers from multiple issues, resulting in security functions |
| 19 |
bypass, local Denial of service, cross-site scripting or PHP variables |
| 20 |
overwrite. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
PHP is a general-purpose scripting language widely used to develop |
| 26 |
web-based applications. It can run inside a web server using the |
| 27 |
mod_php module or the CGI version and also stand-alone in a CLI. |

Description |
| 46 |
=========== |
| 47 |
|
| 48 |
Multiple vulnerabilities have been found and fixed in PHP: |
| 49 |
|
| 50 |
* a possible $GLOBALS variable overwrite problem through file upload |
| 51 |
handling, extract() and import_request_variables() (CVE-2005-3390) |
| 52 |
|
| 53 |
* a local Denial of Service through the use of the session.save_path |
| 54 |
option (CVE-2005-3319) |
| 55 |
|
| 56 |
* an issue with trailing slashes in allowed basedirs (CVE-2005-3054) |
| 57 |
|
| 58 |
* an issue with calling virtual() on Apache 2, allowing to bypass |
| 59 |
safe_mode and open_basedir restrictions (CVE-2005-3392) |
| 60 |
|
| 61 |
* a problem when a request was terminated due to memory_limit |
| 62 |
constraints during certain parse_str() calls (CVE-2005-3389) |
| 63 |
|
| 64 |
* The curl and gd modules allowed to bypass the safe mode |
| 65 |
open_basedir restrictions (CVE-2005-3391) |
| 66 |
|
| 67 |
* a cross-site scripting (XSS) vulnerability in phpinfo() |
| 68 |
(CVE-2005-3388) |
| 69 |
|
| 70 |
Impact |
| 71 |
====== |
| 72 |
|
| 73 |
Attackers could leverage these issues to exploit applications that are |
| 74 |
assumed to be secure through the use of proper register_globals, |
| 75 |
safe_mode or open_basedir parameters. Remote attackers could also |
| 76 |
conduct cross-site scripting attacks if a page calling phpinfo() was |
| 77 |
available. Finally, a local attacker could cause a local Denial of |
| 78 |
Service using malicious session.save_path options. |
| 79 |
|
| 80 |
Workaround |
| 81 |
========== |
| 82 |
|
| 83 |
There is no known workaround that would solve all issues at this time. |
| 84 |
|
| 85 |
Resolution |
| 86 |
========== |
| 87 |
|
| 88 |
All PHP users should upgrade to the latest version: |
| 89 |
|
| 90 |
# emerge --sync |
| 91 |
# emerge --ask --oneshot --verbose dev-php/php |
| 92 |
|
| 93 |
All mod_php users should upgrade to the latest version: |
| 94 |
|
| 95 |
# emerge --sync |
| 96 |
# emerge --ask --oneshot --verbose dev-php/mod_php |
| 97 |
|
| 98 |
All php-cgi users should upgrade to the latest version: |
| 99 |
|
| 100 |
# emerge --sync |
| 101 |
# emerge --ask --oneshot --verbose dev-php/php-cgi |
| 102 |
