Name of the Vulnerable Software and Affected Versions Contiki versions through 3.0

Description The issue is related to an integer overflow in the uIP TCP/IP Stack component when parsing TCP MSS options of IPv4 network packets in the uip process function in net/ipv4/uip.c. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For Contiki versions through 3.0, consider disabling the uip process function in net/ipv4/uip.c as a temporary workaround to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
