Description:
Toni Koivunen has reported a vulnerability in phpMyAdmin, which can be exploited by malicious people to conduct HTTP response splitting attacks.
Some input passed to "libraries/header_http.inc.php" isn't properly sanitised before being returned to the user. This can be exploited to include arbitrary HTTP headers in a response sent to the user.
Successful exploitation requires that "register_globals" is enabled.
It is also possible to disclose the full path to certain scripts by accessing them directly.
The vulnerability has been reported in versions prior to 2.6.4-pl4 and in version 2.7.0-beta1.
Solution:
Update to version 2.6.4-pl4.
