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

Description An issue exists in the uIP TCP/IP Stack component of Contiki when calculating the checksums for IP packets in the upper layer chksum function in net/ipv4/uip.c, leading to an Out-of-Bounds Read. This can allow a remote attacker to cause a denial of service.

Recommendations For Contiki versions through 3.0, as a temporary workaround, consider restricting access to the upper layer chksum function in net/ipv4/uip.c until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
