VAR-202007-0644
Vulnerability from variot - Updated: 2023-12-18 12:35RIOT 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. RIOT Exists in a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. RIOT RIOT-OS is a set of operating systems used in the field of Internet of Things. Remote attackers can use this vulnerability to execute arbitrary code on the system with the help of specially crafted parameters

VAR-201908-0940
Vulnerability from variot - Updated: 2023-12-18 11:59In 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 Contains a resource management vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. RIOT RIOT-OS is a set of operating systems used in the field of Internet of Things. The TCP implementation (gnrc_tcp) in RIOT 2019.07 and earlier versions has a security vulnerability. An attacker could use this vulnerability to cause an infinite loop, resulting in a denial of service
