CyberRota Analysis
AI-GeneratedThe rpcinfo utility in rpcbind is vulnerable to a stack-based buffer overflow due to insufficient bounds checking when processing version numbers from RPCBPROC_DUMP replies. This flaw can lead to crashes or denial of service for users or administrators executing the `rpcinfo -s` command against a malicious rpcbind endpoint. Organizations using rpcbind should prioritize patching or mitigating this vulnerability to prevent potential disruptions in service.
Original NVD Description
A stack-based buffer overflow was found in rpcbind's rpcinfo utility. In rpcbdump() short mode (used by `rpcinfo -s`), version numbers from a remote RPCBPROC_DUMP reply are written into a fixed-size stack buffer without bounds checking. A user or administrator who runs `rpcinfo -s` against a malicious or compromised rpcbind endpoint could experience a crash or denial of service of the rpcinfo client.
