iDefense Security Advisory 09.26.11 - Novell Groupwise Memory Corruption
Posted Sep 28, 2011
Authored by iDefense Labs | Site idefense.com

iDefense Security Advisory 09.26.11 - Remote exploitation of a memory corruption vulnerability in Novell Inc.'s GroupWise could allow an attacker to execute arbitrary code with the privileges of the affected service. This vulnerability is present in the calendar processing code, which resides within the GroupWise Internet Agent (GWIA) process. The vulnerability occurs when parsing a malformed calendar recurrence (RRULE) that recurs yearly. When adding a sequence of dates, it is possible to trigger an invalid array indexing vulnerability, and write beyond the bounds of a heap buffer. This can lead to the execution of arbitrary code. Novell GroupWise 8.0x up to (and including) 8.02HP2 are vulnerable.

I. BACKGROUND

GroupWise is Novell's messaging platform, and includes support for
email, calendaring, and instant messaging. More information is available
at the following website:

http://www.novell.com/products/groupwise/

II. DESCRIPTION

Remote exploitation of a memory corruption vulnerability in Novell
Inc.'s GroupWise could allow an attacker to execute arbitrary code with
the privileges of the affected service.

This vulnerability is present in the calendar processing code, which
resides within the GroupWise Internet Agent (GWIA) process. The
vulnerability occurs when parsing a malformed calendar recurrence
(RRULE) that recurs yearly. When adding a sequence of dates, it is
possible to trigger an invalid array indexing vulnerability, and write
beyond the bounds of a heap buffer. This can lead to the execution of
arbitrary code.

III. ANALYSIS

Exploitation of this vulnerability results in the execution of arbitrary
code with the privileges of the affected service. On Windows, the GWIA
process runs with SYSTEM privileges. In order to exploit this
vulnerability, an attacker simply needs to send an email to a valid
user, and attach the malicious calendar file to the email. The targeted
user does not need to download or view the email; processing of the iCal
file occurs automatically on the server as soon as the email is received
by the server.

IV. DETECTION

Novell GroupWise 8.0x up to (and including) 8.02HP2 are vulnerable.

V. WORKAROUND

iDefense is currently unaware of any workaround for this issue.
