Computer Associates Alert Notification Server Multiple Buffer Overflow
Vulnerabilities
------------------------------------------------------------------------


SUMMARY

Computer Associates Alert Notification Server is "used by several CA
products, including eTrust Integrated Threat Management, to provide
notifications to console users". Remote exploitation of multiple buffer
overflow vulnerabilities in Computer Associates International Inc.'s (CA)
Threat Manager allows attackers to execute arbitrary code with SYSTEM
privileges.

DETAILS

When Computer Associates Threat Manager is installed, it also installs the
Alert Notification Server (alert.exe) which registers an RPC interface
with the GUID 3d742890-397c-11cf-9bf1-00805f88cb72. This interface
contains stack-based buffer overflow vulnerabilities within the handling
code for several RPC operation codes.

Analysis:
Exploitation allows an attacker to execute code with SYSTEM privileges on
the targeted host.

The vulnerable code can be reached remotely using the SMB protocol. As
such, valid credentials are required to exploit this vulnerability on
Windows XP and newer systems. Windows 2000 based installations do not
require credentials.

Detection:
iDefense confirmed that the Alert Notification Server included with
Computer Associates International Inc.'s eTrust Integrated Threat
Management r8 for Windows is vulnerable.

Vendor response:
" CA has provided an update to address the vulnerabilities. The updated
Alert service must be manually installed. "
