Descripción técnica

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.
