SquirrelMail Multiple Cross-Site Scripting and IMAP Injection Vulnerabilities

SquirrelMail is susceptible to multiple cross-site scripting and IMAP-injection
vulnerabilities. These issues are due to the application's failure to properly
sanitize user-supplied input.

An attacker may leverage any of the cross-site scripting issues to have
arbitrary script code executed in the browser of an unsuspecting user in the
context of the affected site. This may facilitate the theft of cookie-based
authentication credentials as well as other attacks.

An attacker may leverage the IMAP-injection issue to execute arbitrary IMAP
commands on the configured IMAP server. This may aid attackers in further
attacks as well as allow them to exploit latent vulnerabilities in the IMAP
server.

An exploit is not required to carry out these attacks.

Solution:
The vendor has committed fixes to the SquirrelMail CVS repository. Snapshots of
the current development version are available from the vendor. For further
information on obtaining fixed versions, contact the vendor.

Version 1.4.6 - CVS
-------------------
  - Security: MagicHTML fix for comments in styles which allowed
    for cross site scripting when using Internet Explorer (reported
    by Scott Hughes) [CVE-2006-0195].
  - Multi-line encoded headers were being deleted (#1394667).
  - Security: Prohibit IMAP injection attempts (reported by Vicente
    Aguilera) [CVE-2006-0377].
  - Handle unsollicited responses inside SORT responses properly.
  - Security: Fix possible cross site scripting through the right_main
    parameter of webmail.php. This now uses a whitelist of acceptable
    values. [CVE-2006-0188]
  - Removed invalid STARTTLS check from configtest.php script.
  - Added Georgian language support.

Hello All,

It is my proud pleasure to announce the final release of SquirrelMail
1.4.6.

This release is very important, and we strongly advise everybody to
update to the latest release.

Security Update
===============
This version contains a number of security updates that were brought
to our attention via a number of sources.

- In webmail.php, the right_frame parameter was not properly sanitized
  to deal with very lenient browsers, which allowed for cross site
  scripting or frame replacing. [CVE-2006-0188]

- In the MagicHTML function, some very obscure constructs were
  discovered to be exploitable: 'u\rl' was interpreted as 'url' (privacy
  concern), and comments could be inside keywords (allows for cross site
  scripting). Both only affect Internet Explorer users. Found by Martijn
  Brinkers and Scott Hughes. [CVE-2006-0195]

- The function sqimap_mailbox_select did not strip newlines from the
  mailbox parameter, and thereby allowed for IMAP command injection.
  Found by Vicente Aguilera. [CVE-2006-0377]

following address:

We strongly encourage any persons uncovering Security issues to
contact the SquirrelMail team via security@squirrelmail.org.


In This Release
===============
This release contains mostly bug fixes, including corrections for PHP
behaviour changes in file handling, and some data types. Especially
running SquirrelMail on the most recent PHP versions should be much
improved.

For further information about the changes involved in this release,
please see the ChangeLog and ReleaseNotes files included with the
release.
