    <p>
    SquirrelMail is a webmail package written in PHP. It supports IMAP
    and SMTP protocols.

  <description>
    <p>
    SquirrelMail does not validate the right_frame parameter in
    webmail.php, possibly allowing frame replacement or cross-site
    scripting (CVE-2006-0188). Martijn Brinkers and Scott Hughes discovered
    that MagicHTML fails to handle certain input correctly, potentially
    leading to cross-site scripting (only Internet Explorer,
    CVE-2006-0195). Vicente Aguilera reported that the
    sqimap_mailbox_select function did not strip newlines from the mailbox
    or subject parameter, possibly allowing IMAP command injection
    (CVE-2006-0377).
    </p>
  </description>
  <impact type="low">
    <p>
    By exploiting the cross-site scripting vulnerabilities, an
    attacker can execute arbitrary scripts running in the context of the
    victim's browser. This could lead to a compromise of the user's webmail
    account, cookie theft, etc. A remote attacker could exploit the IMAP
    command injection to execute arbitrary IMAP commands on the configured
    IMAP server.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All SquirrelMail users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=mail-client/squirrelmail-1.4.6"</code>
    <p>
    Note: Users with the vhosts USE flag set should manually use
    webapp-config to finalize the update.
    </p>
