CyberRota Analysis
This is a critical severity vulnerability with a CVSS score of 9.8. Its EPSS score suggests a 18.5% probability of exploitation in the next 30 days. It may lead to a denial-of-service condition.
Original NVD Description
An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. The code that reassembles fragmented packets fails to properly validate the total length of an incoming packet specified in its IP header, as well as the fragmentation offset value specified in the IP header. By crafting a packet with specific values of the IP header length and the fragmentation offset, attackers can write into the .bss section of the program (past the statically allocated buffer that is used for storing the fragmented data) and cause a denial of service in uip_reass() in uip.c, or possibly execute arbitrary code on some target architectures.
