CVE-2019-15134
RIOT through 2019.07 contains a memory leak in the TCP implementation (gnrc_tcp), allowing an attacker to consume all memory available for network packets and thus effectively stopping all network threads from working.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
RIOT through 2019.07 contains a memory leak in the TCP implementation (gnrc_tcp), allowing an attacker to consume all memory available for network packets and thus effectively stopping all network threads from working. This is related to _receive in sys/net/gnrc/transport_layer/tcp/gnrc_tcp_eventloop.c upon receiving an ACK before a SYN.
