TITLE:
GroupWise Client Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA16227

VERIFY ADVISORY:
http://secunia.com/advisories/16227/

CRITICAL:
Not critical

IMPACT:
Privilege escalation, DoS

WHERE:
Local system

SOFTWARE:
Novell Groupwise 6.x
http://secunia.com/product/86/

DESCRIPTION:
Francisco Amato has reported a vulnerability in GroupWise Client,
which can be exploited by malicious, local users to cause a DoS
(Denial of Service) or potentially gain escalated privileges.

The vulnerability is caused due a boundary error in the client when
parsing the file containing the labels of different views (i.e.
GWVW02??.INI). This can be exploited to cause a buffer overflow when
the client attempts to log into the post office.

Successful exploitation requires permissions to modify the
GWVW02??.INI files, which is normally restricted to administrative
users.

The vulnerability has been reported in version 6.5.

SOLUTION:
A fix is available in any build of GroupWise 6.5 client dated after
2005-07-15.
