Medienbericht

rpcapd memory leak in libpcap before 1.10.7

rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client, but it never frees the memory, so it leaks memory even under normal use.  A malicious client can cause the server to leak memory substantially faster.
