Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell GroupWise. Authentication is not required
to exploit this vulnerability.
The specific flaw exists within the gwia.exe module responsible for parsing
e-mail messages received by the server. When the code encounters a
Content-Type header it proceeds to parse out the entities within its contents,
separated by a semicolon. The process does not properly check the size of
these values before copying them individually to a fixed-length stack buffer.
This can be abused by an attacker to overflow the buffer and subsequently
execute arbitrary code under the context of the SYSTEM user. Vendor Response

The GroupWise Internet Agent (GWIA) has a vulnerability in the way that it
parses multiple values within the "Content-Type" header of a received message,
which could potentially allow an unauthenticated remote attacker to execute
arbitrary code on vulnerable installations of GWIA. Affected versions:
GroupWise 8.0x, 8.01x, 8.02. Previous versions of GroupWise are likely also
vulnerable but are no longer supported. Customers on earlier versions of
GroupWise should, at a minimum, upgrade their GWIAs and associated Domains to
version 8.02HP in order to secure their system. This vulnerability was
discovered and reported by Anonymous working with TippingPoint's Zero Day

Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell GroupWise. Authentication is not required
to exploit this vulnerability.
The specific flaw exists within the gwwww1.dll module responsible for parsing
VCALENDAR data within e-mail messages. When the code encounters a RRULE
variable it allocates memory for 0x800 bytes for the variable's contents, a
list of numbers. It then proceeds to copy the numbers from the request while
there are numbers to parse. By specifying a large amount of comma-separated
values within an RRULE, an attacker can overflow the buffer and execute
arbitrary code under the context of the SYSTEM user. Vendor Response Novell

Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell GroupWise. Authentication is not required
to exploit this vulnerability.
The specific flaw exists within the gwwww1.dll module responsible for parsing
VCALENDAR data within e-mail messages. When the code encounters a COMMENT
variable it allocates up to 0xFFFF bytes for the variable's value. It then
proceeds to copy the value into the fixed-length buffer without checking if it
will fit. By specifying a large enough string in the e-mail, an attacker can
overflow the buffer and execute arbitrary code under the context of the SYSTEM
user. Vendor Response Novell states:

Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell GroupWise. Authentication is not required

The specific flaw exists within the gwia.exe module responsible for parsing
e-mail messages received by the server. When the code encounters a
Content-Type header it proceeds to parse out the numbers within its contents.
The process does not properly check for signed integers and if it encounters
one, it loops excessively while writing to the stack. This can be abused by a
remote attacker to execute arbitrary code under the context of the SYSTEM
user. Vendor Response Novell states:

Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell Groupwise Internet Agent. Authentication is
not required to exploit this vulnerability.
The flaw exists within the IMAP server component which listens by default on
TCP port 143. When handling an IMAP LIST command with a large parameter the
process attempts to free the same memory twice. A remote attacker can exploit
this vulnerability to execute arbitrary code under the context of the IMAP
server. Vendor Response Novell states:

Description: The GroupWise Internet Agent has a vulnerability in its IMAP
component that could potentially allow an unauthenticated remote attacker to
execute arbitrary code on vulnerable installations of GWIA where IMAP services
are enabled. Affected versions: GroupWise 8.0x, 8.01x, 8.02. Previous versions
of GroupWise are likely also vulnerable but are no longer supported. Customers
on earlier versions of GroupWise should, at a minimum, upgrade their GWIAs and
associated Domains to version 8.02HP in order to secure their system. This
