Description
An issue was discovered in picoTCP and picoTCP-NG 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 reads that lead to Denial-of-Service.
Affected configurations
• altran picotcp (<= 1.7.0)
• altran picotcp-ng (<= 1.7.0)
