In RIOT 2019.07, the MQTT-SN implementation (asymcute) mishandles errors occurring during a read operation on a UDP socket. The receive loop ends. This allows an attacker (via a large packet) to prevent a RIOT MQTT-SN client from working until the device is restarted.

RIOT 2019.07 contains a NULL pointer dereference in the MQTT-SN implementation (asymcute), potentially allowing an attacker to crash a network node running RIOT. This requires spoofing an MQTT server response. To do so, the attacker needs to know the MQTT MsgID of a pending MQTT protocol message and the ephemeral port used by RIOT's MQTT implementation. Additionally, the server IP address is required for spoofing the packet.

In the TCP implementation (gnrc_tcp) in RIOT through 2019.07, the parser for TCP options does not terminate on all inputs, allowing a denial-of-service, because sys/net/gnrc/transport_layer/tcp/gnrc_tcp_option.c has an infinite loop for an unknown zero-length option.

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.

RIOT RIOT-OS version after commit 7af03ab624db0412c727eed9ab7630a5282e2fd3 contains a Buffer Overflow vulnerability in sock_dns, an implementation of the DNS protocol utilizing the RIOT sock API that can result in Remote code executing. This attack appears to be exploitable via network connectivity.

The riot-compiler version version 2.3.21 has an issue in a regex (Catastrophic Backtracking) thats make it unusable under certain conditions.

Stack-based buffer overflow in the ipv6_addr_from_str function in sys/net/network_layer/ipv6/addr/ipv6_addr_from_str.c in RIOT prior to 2017-04-25 allows local attackers, and potentially remote attackers, to cause a denial of service or possibly have unspecified other impact via a malformed IPv6 address.

SQL injection vulnerability in index.php in RiotPix 0.61 and earlier allows remote attackers to execute arbitrary SQL commands via the username parameter. NOTE: some of these details are obtained from third party information.

SQL injection vulnerability in read.php in RiotPix 0.61 and earlier allows remote attackers to execute arbitrary SQL commands via the forumid parameter.
