GHSA-37Q6-VW96-Q6Q8

Vulnerability from github – Published: 2022-05-24 17:36 – Updated: 2022-05-24 17:36

Details

An issue was discovered in Contiki through 3.0 and Contiki-NG through 4.5. The code for parsing Type A domain name answers in ip64-dns64.c doesn't verify whether the address in the answer's length is sane. Therefore, when copying an address of an arbitrary length, a buffer overflow can occur. This bug can be exploited whenever NAT64 is enabled.
