Package: phpbb2
Version: 2.0.21-7
Severity: grave
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for phpbb2.

CVE-2008-4125[0]:
| The search function in phpBB 2.x provides a search_id value that
| leaks the state of PHP's PRNG, which allows remote attackers to
| obtain potentially sensitive information, as demonstrated by a
| cross-application attack against WordPress, a different
| vulnerability than CVE-2006-0632.

This can create security issues in other web applications that run on 
the same server.

This issue could also be fixed by modifying php. According to the 
announcement, this will be done in the next release of suhosin, but I 
am not sure that this will be in time for lenny.

Please also check phpbb3.

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
