ZDI-08-063: Novell eDirectory dhost.exe Content-Length Header Heap
Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-063
October 8, 2008
- -- CVE ID:
CVE-2008-4478
- -- Affected Vendors:
Novell
- -- Affected Products:
Novell eDirectory
- -- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 3710.

http://www.tippingpoint.com
- -- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory. Authentication is not
required to exploit this vulnerability.
The specific flaw resides in the web console running on TCP ports 8028
and 8030. The server exposes a web interface and accepts SOAP
connections. While parsing the Content-Length header within a SOAP
request an integer overflow can occur. This integer overflow triggers a
subsequent overflow during a memory copy operation leading to arbitrary
code execution under the context of the SYSTEM user.
- -- Vendor Response:
Novell has issued an update to correct this vulnerability. More
details can be found at:

ZDI-08-064: Novell eDirectory dhost.exe Accept Language Header Heap
Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-064
October 8, 2008
- -- CVE ID:
CVE-2008-4479
- -- Affected Vendors:
Novell
- -- Affected Products:
Novell eDirectory
- -- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 6084.
For further product information on the TippingPoint IPS, visit:
http://www.tippingpoint.com
- -- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory. Authentication is not
required to exploit this vulnerability.
The specific flaw resides in the web console running on TCP ports 8028
and 8030. The server exposes a web interface and accepts SOAP
connections. The service copies the contents of the Accept-Language
header within a SOAP request into a fixed-length buffer without any
bounds checking. If an attacker sends a specially crafted request it
will trigger an overflow during a memory copy operation leading to
arbitrary code execution under the context of the SYSTEM user.
- -- Vendor Response:
Novell has issued an update to correct this vulnerability. More
details can be found at:

ZDI-08-065: Novell eDirectory Core Protocol Opcode 0x0F Heap Overflow
Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-065
October 8, 2008
- -- CVE ID:
CVE-2008-4478
- -- Affected Vendors:
Novell
- -- Affected Products:
Novell eDirectory
- -- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 6178.
For further product information on the TippingPoint IPS, visit:
http://www.tippingpoint.com
- -- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory Server. Authentication is
not required to exploit this vulnerability.
The specific flaw exists within dhost.exe, the service responsible for
directory replication which is bound by default to TCP port 524.
Improper parsing within opcode 0x0F via the Netware Core Protocol can
result in an arithmetic calculation based on supplied user-input
resulting in an integer overflow that will be used to copy into a heap
buffer. This fault can be leveraged to result in arbitrary code
execution.
- -- Vendor Response:
Novell has issued an update to correct this vulnerability. More
details can be found at:
http://www.novell.com/support/php/search.do?cmd=displayKC&docType=kc&externalId=7001184&sliceId=1&docTypeID=DT_TID_1_1&dialogID=78066829&stateId=0%200%2078062953
