Title: Microsoft RPCSS DCERPC DCOM Object Activation Packet Length Heap Corruption Vulnerability
Severity: CRITICAL
Description:
Microsoft Windows uses Remote Procedure Calls (RPC) for client-server communications in a distributed computing environment (DCE).
A remotely exploitable heap corruption vulnerability has been discovered in RPC. This issue exists in the RPCSS Service and occurs due to insufficient sanity checks when handling length values located within DCERPC DCOM object activation packets. By transmitting a sequence of four to five of these malformed activation packets, an attacker may be capable of corrupting sensitive locations within heap memory with user-supplied data. As a result, an attacker may be capable of triggering a condition under which a controlled word may be written to an arbitrary location in memory. This could ultimately allow for the execution of arbitrary code with SYSTEM privileges.
A remote attacker could exploit this issue by sending a malformed RPC message to an affected system via any port that listens for RPC messages, such as TCP ports 135, 139, 445 and 593 or UDP ports 135, 137, 138 and 445. COM Internet Services may be expose this issue via ports 80 and 443.
eEye released an advisory disclosing details about the issue they reported that was addressed in MS03-039. It is currently not known if this information is associated with CAN-2003-0528. The other buffer overrun reported in MS03-039 and described in BID 8459 may be applicable to CAN-2003-0528. The appropriate updates will be made when further CVE information becomes available.
