<p>
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.
</p>
</background>
<description>
<p>
Multiple vulnerabilities have been found and fixed in PHP:
</p>
<ul>
<li>a possible $GLOBALS variable overwrite problem through file
upload handling, extract() and import_request_variables()
(CVE-2005-3390)</li>
<li>a local Denial of Service through the use of
the session.save_path option (CVE-2005-3319)</li>
<li>an issue with
trailing slashes in allowed basedirs (CVE-2005-3054)</li>
<li>an issue
with calling virtual() on Apache 2, allowing to bypass safe_mode and
open_basedir restrictions (CVE-2005-3392)</li>
<li>a problem when a
request was terminated due to memory_limit constraints during certain
parse_str() calls (CVE-2005-3389)</li>
<li>The curl and gd modules
allowed to bypass the safe mode open_basedir restrictions
(CVE-2005-3391)</li>
<li>a cross-site scripting (XSS) vulnerability in
phpinfo() (CVE-2005-3388)</li>
</ul>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround that would solve all issues at this
time.
</p>
</workaround>
<resolution>
<p>
All PHP users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php</code>
<p>
All mod_php users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/mod_php</code>
<p>
All php-cgi users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose dev-php/php-cgi</code>
</resolution>
