CVE-2019-10056

An issue was discovered in Suricata 4.1.3. The code mishandles the case of sending a network packet with the right type, such that the function DecodeEthernet in decode-ethernet.c is executed a second time. At this point, the algorithm cuts the first part of the packet and doesn't determine the...

Design/Logic Flaw

RIOT through 2019.07 contains a memory leak in the TCP implementation gnrctcp, 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/transportlayer/tcp/gnrctcpeventloop.c...
