Dnsmasq 2.86 has a heap-based buffer overflow in print_mac (called from log_packet and dhcp_reply). Reference: https://github.com/google/oss-fuzz-vulns/blob/main/vulns/dnsmasq/OSV-2021-933.yaml https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35887
Created dnsmasq tracking bugs for this issue: Affects: fedora-all [bug 2048926]
Because print_mac also uses daemon->namebuff as printout buffer, I expect this is too related to extract_name fixes. After applying PR [1] I were unable to reproduce this issue anymore. It seems to be related, probably this is also bogus issue. 1. https://github.com/google/oss-fuzz/pull/7293
