GHSA-37q6-vw96-q6q8 PUBLISHED CVSS 9.300000190734863 CRITICAL

Record from GitHub Advisory Database · Published May 24, 2022

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.
