VERIFY ADVISORY:
http://secunia.com/advisories/20888/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Novell GroupWise 7.x
http://secunia.com/product/5667/

http://secunia.com/product/86/
Novell Groupwise 5.x

DESCRIPTION:
A vulnerability has been reported in Novell GroupWise, which can be
exploited by malicious users to bypass certain security
restrictions.

The vulnerability is caused due to an error within the GroupWise
Windows Client API. This can be exploited to gain programmatic access
to certain non-authorised emails within the same authenticated post
office.

The vulnerability has been reported in the following versions:
* Novell GroupWise 5.x
* Novell GroupWise 6.0
* Novell GroupWise 6.5
* Novell GroupWise 7
* Novell GroupWise 32-bit Client

SOLUTION:
Apply updates.

GroupWise 6.5:
Apply SP6 Client Update 1 (dated 2006-06-27)
http://support.novell.com/filefinder/16963/index.html

GroupWise 7:
Apply GroupWise 7 SP1 (dated 2006-06-19)
http://support.novell.com/filefinder/20641/index.html

The vendor recommends users of unsupported GroupWise versions (5.x
and 6) to upgrade to either GroupWise 6.5 SP6 Update 1 or to
GroupWise 7 SP1.

NOTE: The vendor recommends that older Windows clients must be locked
out via ConsoleOne after the update. If Blackberry Enterprise Server
(BES) is installed in a GroupWise 7 environment then the lock out
should based on client date rather than client version. The
recommended lock out date is 2006-06-13 to ensure that the system is
not vulnerable.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
