ZDI-09-074: Multiple Vendor Hummingbird STR Service Stack Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-09-074
October 28, 2009

-- Affected Vendors:
    EMC
    OpenText

-- Affected Products:
    EMC Documentum eRoom
    OpenText Hummingbird
    OpenText Search Server

-- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 6259.

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
systems with vulnerable installations of EMC Documentum eRoom, OpenText
Hummingbird and OpenText Search Server. Authentication is not required
to exploit this vulnerability.

The specific flaw exists in the Hummingbird STR service (STRsvc.exe)
which listens by default on TCP port 10500. The STRlib.dll module
receives network packet data into a static stack buffer. By providing a
large enough packet, this buffer can overflow. Exploitation allows
remote attackers to execute arbitrary code under the context of the
SYSTEM user.

-- Vendor Response:
EMC states:
This issue has been resolved in EMC Documentum eRoom 7.4.2. EMC strongly
recommends customers upgrade to EMC Documentum eRoom 7.4.2. More
information on this can be found an powerlink.emc.com (Knowledge Base
esg99041).

OpenText states:
This issue has been resolved in the latest Search Server 6.0 and 6.1
patches for all platforms. More information on the fix can be found in
OpenText Knowledge Base 14816981 (login is required to access the
content).
