CVE-2019-1000006 1 Riot-os 1 Riot 2024-08-05 9.8 Critical
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.
CVE-2019-17389 1 Riot-os 1 Riot 2024-08-05 7.5 High
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.
CVE-2019-16754 1 Riot-os 1 Riot 2024-08-05 7.5 High
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.
CVE-2019-15702 1 Riot-os 1 Riot 2024-08-05 7.5 High
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.
CVE-2019-15134 1 Riot-os 1 Riot 2024-08-05 N/A
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.
CVE-2020-15350 1 Riot-os 1 Riot 2024-08-04 9.8 Critical
RIOT 2020.04 has a buffer overflow in the base64 decoder. The decoding function base64_decode() uses an output buffer estimation function to compute the required buffer capacity and validate against the provided buffer size. The base64_estimate_decode_size() function calculates the expected decoded size with an arithmetic round-off error and does not take into account possible padding bytes. Due to this underestimation, it may be possible to craft base64 input that causes a buffer overflow.
CVE-2021-41061 1 Riot-os 1 Riot 2024-08-04 5.5 Medium
In RIOT-OS 2021.01, nonce reuse in 802.15.4 encryption in the ieee820154_security component allows attackers to break encryption by triggering reboots.

RIOT-OS 2021.01 before commit 44741ff99f7a71df45420635b238b9c22093647a contains a buffer overflow which could allow attackers to obtain sensitive information.
CVE-2021-31662 1 Riot-os 1 Riot 2024-08-03 7.5 High
RIOT-OS 2021.01 before commit 07f1254d8537497552e7dce80364aaead9266bbe contains a buffer overflow which could allow attackers to obtain sensitive information.
CVE-2021-31660 1 Riot-os 1 Riot 2024-08-03 7.5 High
RIOT-OS 2021.01 before commit 85da504d2dc30188b89f44c3276fc5a25b31251f contains a buffer overflow which could allow attackers to obtain sensitive information.
CVE-2021-27697 1 Riot-os 1 Riot 2024-08-03 9.8 Critical
RIOT-OS 2021.01 contains a buffer overflow vulnerability in sys/net/gnrc/routing/rpl/gnrc_rpl_validation.c through the gnrc_rpl_validation_options() function.
CVE-2021-27698 1 Riot-os 1 Riot 2024-08-03 9.8 Critical
RIOT-OS 2021.01 contains a buffer overflow vulnerability in /sys/net/gnrc/routing/rpl/gnrc_rpl_control_messages.c through the _parse_options() function.
CVE-2021-27427 1 Riot-os 1 Riot 2024-08-03 7.3 High
RIOT OS version 2020.01.1 is vulnerable to integer wrap-around in its implementation of calloc function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.
CVE-2021-27357 1 Riot-os 1 Riot 2024-08-03 9.8 Critical
RIOT-OS 2020.01 contains a buffer overflow vulnerability in /sys/net/gnrc/routing/rpl/gnrc_rpl_control_messages.c.
CVE-2023-33973 1 Riot-os 1 Riot 2024-08-02 7.5 High
RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. In versions 2023.01 and prior, an attacker can send a crafted frame which is forwarded by the device. During encoding of the packet a NULL pointer dereference occurs. This crashes the device leading to denial of service. A patch is available at pull request 19678. There are no known workarounds.
CVE-2023-33975 1 Riot-os 1 Riot 2024-08-02 9.8 Critical
RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. In version 2023.01 and prior, an attacker can send a crafted frame to the device resulting in an out of bounds write in the packet buffer. The overflow can be used to corrupt other packets and the allocator metadata. Corrupting a pointer will easily lead to denial of service. While carefully manipulating the allocator metadata gives an attacker the possibility to write data to arbitrary locations and thus execute arbitrary code. This issue is fixed in pull request 19680. As a workaround, disable support for fragmented IP datagrams.
CVE-2023-33974 1 Riot-os 1 Riot 2024-08-02 7.5 High
RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. In versions 2023.01 and prior, an attacker can send multiple crafted frames to the device to trigger a race condition. The race condition invalidates assumptions about the program state and leads to an invalid memory access resulting in denial of service. This issue is patched in pull request 19679. There are no known workarounds.
CVE-2023-24818 1 Riot-os 1 Riot 2024-08-02 7.5 High
RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2022.10, an attacker can send a crafted frame to the device resulting in a NULL pointer dereference. During forwarding of a fragment an uninitialized entry in the reassembly buffer is used. The NULL pointer dereference triggers a hard fault exception resulting in denial of service. Version 2022.10 fixes this issue. As a workaround, disable support for fragmented IP datagrams or apply the patches manually.
