What is CVE-2002-0391?

The vulnerability arises from an integer overflow in the xdr_array function within RPC servers, particularly those utilizing libc, glibc, or derivatives of SunRPC, including dietlibc. Attackers can exploit this flaw by sending an excessive number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd, which may lead to the execution of arbitrary code. This could potentially compromise the integrity and confidentiality of the system, allowing unauthorized access and manipulation of sensitive data.
