‘An integer overflow vulnerability was reported in the rpc.pcnfsd service within the several systems. The rpc.pcnfsd daemon handles requests from PC-NFS clients for authentication services on remote machines. These services include authentication for mounting and for print spooling. The vulnerability is triggered when parsing crafted RPC requests. A remote attacker can leverage this vulnerability by sending a crafted RPC message to the target host, to potentially inject and execute arbitrary code.’.
