BACKGROUND Computer Associates Alert Notification Server is used by several CA products, including eTrust Integrated Threat Management, to provide notifications to console users. II. DESCRIPTION Remote exploitation of multiple buffer overflow vulnerabilities in Computer Associates International Inc.'s Alert Notification Service may allow an authenticated attacker to execute arbitrary code with SYSTEM privileges. The Alert Service is a component of multiple Computer Associates' products. It is used to provide status updates and notifications regarding various system events. It implements an RPC interface with GUID 3d742890-397c-11cf-9bf1-00805f88cb72. Multiple buffer overflows exist in the handlers for various opcodes. In each case, unsafe library functions are used to copy attacker supplied data into fixed size stack buffers. By making specially crafted requests, attackers are able to cause an exploitable buffer overflow. III. ANALYSIS Exploitation of these vulnerabilities allows an attacker to execute arbitrary code with SYSTEM privileges. In order to exploit these vulnerabilities, it is necessary for an attacker to have valid domain credentials. IV. DETECTION iDefense confirmed the existence of these vulnerabilities with Computer Associates' Threat Manager for the Enterprise version 8.1. Other products that contain the Alert Notification Service are suspected to be vulnerable as well. V. WORKAROUND iDefense is currently unaware of any effective workaround for these issues. VI. VENDOR RESPONSE Computer Associates has addressed these issues by providing updates. More information is available in their advisory at the following URL. https://support.ca.com/irj/portal/anonymous/phpsupcontent?contentID=173103 VII.
