Kerentanan Missing Release of Memory after Effective Lifetime. Skor CVSS 3.1 4.3 (Medium) menurut tcpdump.org.

Deskripsi (NVD)

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.
