CVE-2019-15702
Last modified
CVE-2019-15702 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 1.44% chance of exploitation in the next 30 days.
