CVE-2020-24334
Last modified
CVE-2020-24334 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. The code that processes DNS responses in uIP through 1.0, as used in Contiki and Contiki-NG, does not check whether the number of responses specified in the DNS packet header corresponds to the response data available in the DNS packet, leading to an out-of-bounds read and Denial-of-Service in resolv.c.. EPSS estimates a 2.40% chance of exploitation in the next 30 days.
