DESCRIPTION:
Stefan Esser has discovered a vulnerability in Dotdeb PHP, which can
be exploited by malicious people to send manipulated e-mail messages
and expose sensitive information.
The "mail()" function adds a "X-PHP-Script" e-mail header with the
PHP_SELF variable and other information. Arbitrary mail headers and
body text can be added by including URL encoded CRLF sequences in the
PATH_INFO part of PHP_SELF, when calling any Dotdeb PHP script that
uses the "mail()" function.
Successful exploitation allows sending of spam mail or getting copies
of sensitive information.
The vulnerability is confirmed in version 5.1.6-0.dotdeb.2. Other
versions may also be affected.
SOLUTION:
Update to version 5.2.0-0.dotdeb.3.
PROVIDED AND/OR DISCOVERED BY:
Stefan Esser, Hardened-PHP Project.
