Synopsis
========
PHP suffers from multiple issues, resulting in security functions
bypass, local Denial of service, cross-site scripting or PHP variables
overwrite.
Background
==========
PHP is a general-purpose scripting language widely used to develop
web-based applications. It can run inside a web server using the
mod_php module or the CGI version and also stand-alone in a CLI.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-php/php < 4.4.0-r4 *>= 4.3.11-r4
>= 4.4.0-r4
2 dev-php/mod_php < 4.4.0-r8 *>= 4.3.11-r4
>= 4.4.0-r8
3 dev-php/php-cgi < 4.4.0-r5 *>= 4.3.11-r5
>= 4.4.0-r5
-------------------------------------------------------------------
3 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Multiple vulnerabilities have been found and fixed in PHP:
* a possible $GLOBALS variable overwrite problem through file upload
handling, extract() and import_request_variables() (CVE-2005-3390)
* a local Denial of Service through the use of the session.save_path
option (CVE-2005-3319)
* an issue with trailing slashes in allowed basedirs (CVE-2005-3054)
* an issue with calling virtual() on Apache 2, allowing to bypass
safe_mode and open_basedir restrictions (CVE-2005-3392)
* a problem when a request was terminated due to memory_limit
constraints during certain parse_str() calls (CVE-2005-3389)
* The curl and gd modules allowed to bypass the safe mode
open_basedir restrictions (CVE-2005-3391)
* a cross-site scripting (XSS) vulnerability in phpinfo()
(CVE-2005-3388)
Impact
======
Attackers could leverage these issues to exploit applications that are
assumed to be secure through the use of proper register_globals,
safe_mode or open_basedir parameters. Remote attackers could also
conduct cross-site scripting attacks if a page calling phpinfo() was
available. Finally, a local attacker could cause a local Denial of
Service using malicious session.save_path options.
Workaround
==========
There is no known workaround that would solve all issues at this time.
Resolution
==========
All PHP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php
All mod_php users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/mod_php
All php-cgi users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php-cgi
