pdns-backend-bind: pdns before version 4.1.2 is vulnerable to a buffer overflow in dnsreplay
CVE-2018-1046 is fixed in 15 products on 1 platform, first by pdns-backend-bind 4.1.1-1ubuntu0.1~esm1, released March 25, 2022. It is not reported as exploited. Patch Radar priority: Routine.
pdns before version 4.1.2 is vulnerable to a buffer overflow in dnsreplay. In the dnsreplay tool provided with PowerDNS Authoritative, replaying a specially crafted PCAP file can trigger a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution. This buffer overflow only occurs when the -ecs-stamp option of dnsreplay is used.
