Several vulnerabilities have been discovered in phpBB, a fully
featured and skinnable flat webforum,

The Common Vulnerabilities and Exposures project identifies the
following problems:


CVE-2005-3310

Multiple interpretation errors allow remote authenticated users to
inject arbitrary web script when remote avatars and avatar
uploading are enabled.

CVE-2005-3415

phpBB allows remote attackers to bypass protection mechanisms that
deregister global variables that allows attackers to manipulate
the behaviour of phpBB.

CVE-2005-3416

phpBB allows remote attackers to bypass security checks when
register_globals is enabled and the session_start function has not
been called to handle a session.

CVE-2005-3417

phpBB allows remote attackers to modify global variables and
bypass security mechanisms.

CVE-2005-3418

Multiple cross-site scripting (XSS) vulnerabilities allow remote
attackers to inject arbitrary web scripts.

CVE-2005-3419

An SQL injection vulnerability allows remote attackers to execute
arbitrary SQL commands.

CVE-2005-3420

phpBB allows remote attackers to modify regular expressions and
execute PHP code via the signature_bbcode_uid parameter.

CVE-2005-3536

Missing input sanitising of the topic type allows remote attackers
to inject arbitrary SQL commands.

CVE-2005-3537

Missing request validation permitted remote attackers to edit
private messages of other users.

The old stable distribution (woody) does not contain phpbb2 packages.

For the stable distribution (sarge) these problems have been fixed in
version 2.0.13+1-6sarge2.

For the unstable distribution (sid) these problems have been fixed in
version 2.0.18-1.

We recommend that you upgrade your phpbb2 packages.
