Preface: System-Dependent IDL Preprocessor Variables The following system-dependent preprocessor variables are used in building the IDL compiler. They are all defined in:
dce-root-dir/dce/src/rpc/idl/idl_compiler/sysdep[.]h
AUTO_HEAP_STACK_THRESHOLD defines an estimate for the maximum size of a stack in a server stub. If the IDL compiler estimates that this amount will be exceeded, objects will be allocated via malloc instead of on the stack.
Background: What is dcerpc protocol VMware? DCERPC (Distributed Computing Environment/Remote Procedure Call) with Microsoft extensions (MSRPC) is used to transparently execute functions on remote servers. To facilitate this process, interfaces are defined using an interface definition language (IDL).
Vulnerability details: The vCenter Server contains a heap-overflow vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger this vulnerability by sending a specially crafted network packet potentially leading to remote code execution.
On 21st October 2024 Broadcom issued an update to advisory CMSA-2024-0019 stating that they had determined patches released on 17th September 2024 did not fully address CVE-2024-38812 and subsequently have issued new patches.
