GHSA-C2MH-8C2G-XWR6

Vulnerability from github – Published: 2022-05-24 17:36 – Updated: 2024-04-04 03:03

Details

An issue was discovered in picoTCP through 1.7.0. The DNS domain name record decompression functionality in pico_dns_decompress_name() in pico_dns_common.c does not validate the compression pointer offset values with respect to the actual data present in a DNS response packet, causing out-of-bounds writes that lead to Denial-of-Service and Remote Code Execution.

Severity ?

9.8 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
