+  <title>phpBB: Multiple vulnerabilities</title>
+  <synopsis>
+    Several vulnerabilities allow remote attackers to gain phpBB administrator
+    rights or expose and manipulate sensitive data.

+  <background>
+    <p>
+    phpBB is an Open Source bulletin board package.

+  <description>
+    <p>
+    It was discovered that phpBB contains a flaw in the session
+    handling code and a path disclosure bug. AnthraX101 discovered that
+    phpBB allows local users to read arbitrary files, if the "Enable remote
+    avatars" and "Enable avatar uploading" options are set (CAN-2005-0259).
+    He also found out that incorrect input validation in
+    "usercp_avatar.php" and "usercp_register.php" makes phpBB vulnerable to
+    directory traversal attacks, if the "Gallery avatars" setting is
+    enabled (CAN-2005-0258).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    Remote attackers can exploit the session handling flaw to gain
+    phpBB administrator rights. By providing a local and a remote location
+    for an avatar and setting the "Upload Avatar from a URL:" field to
+    point to the target file, a malicious local user can read arbitrary
+    local files. By inserting "/../" sequences into the "avatarselect"
+    parameter, a remote attacker can exploit the directory traversal
+    vulnerability to delete arbitrary files. A flaw in the "viewtopic.php"
+    script can be exploited to expose the full path of PHP scripts.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All phpBB users should upgrade to the latest available version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/phpBB-2.0.13&quot;</code>
