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.
