squirrelmail - several vulnerabilities

Four vulnerabilities were discovered in squirrelmail:

• CAN-2004-0519
  Multiple cross-site scripting (XSS) vulnerabilities
  in SquirrelMail 1.4.2 allow remote attackers to execute arbitrary
  script as other users and possibly steal authentication information
  via multiple attack vectors, including the mailbox parameter in
  compose.php.

• CAN-2004-0520
  Cross-site scripting (XSS) vulnerability in mime.php
  for SquirrelMail before 1.4.3 allows remote attackers to insert
  arbitrary HTML and script via the content-type mail header, as
  demonstrated using read_body.php.

• CAN-2004-0521
  SQL injection vulnerability in SquirrelMail before
  1.4.3 RC1 allows remote attackers to execute unauthorized SQL
  statements, with unknown impact, probably via abook_database.php.

• CAN-2004-0639
  Multiple cross-site scripting (XSS) vulnerabilities
  in Squirrelmail 1.2.10 and earlier allow remote attackers to inject
  arbitrary HTML or script via (1) the $mailer variable in
  read_body.php, (2) the $senderNames_part variable in
  mailbox_display.php, and possibly other vectors including (3) the
  $event_title variable or (4) the $event_text variable.

For the current stable distribution (woody), these problems have been
fixed in version 1:1.2.6-1.4.

For the unstable distribution (sid), these problems have been fixed in
2:1.4.3a-0.1 and earlier versions.

We recommend that you update your squirrelmail package.
