TITLE:
PHP Configuration Leakage Vulnerability

SECUNIA ADVISORY ID:
SA10818

VERIFY ADVISORY:
http://www.secunia.com/advisories/10818/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Exposure of sensitive information

WHERE:
From remote

SOFTWARE:
PHP 4.3.x

DESCRIPTION:
A vulnerability has been identified in PHP, potentially allowing
malicious people to view sensitive data or bypass an administrative
restriction.

The problem arises on systems serving multiple virtual hosts using
the Apache web server. Administratively configured settings from one
virtual host may be applied (leaked) to other virtual hosts if the
same Apache child process is used to access the different virtual
hosts.

This can reportedly be exploited to view the source of PHP files,
overwrite "register_globals" settings and more. Other vulnerabilities
may potentially also be exploited via this issue.

The vulnerability has been reported in PHP version 4.3.4 and prior.

SOLUTION:
There is no effective solution.

PROVIDED AND/OR DISCOVERED BY:
Reported by multiple individuals (see the original bug reports for
details).
