Synopsis
PHP suffers from multiple issues, resulting in security functions bypass,
local Denial of service, cross-site scripting or PHP variables overwrite.
2.
Impact Information
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.
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.

Resolution Information
Workaround
There is no known workaround that would solve all issues at this
time.
Resolution
All PHP users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php
|
All mod_php users should upgrade to the latest version:
Code Listing 3.2: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/mod_php
|
All php-cgi users should upgrade to the latest version:
Code Listing 3.3: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php-cgi
|
