Description Adam Mariš 2018-05-17 09:34:11 UTC
An issue has been found in the dnsreplay tool provided with PowerDNS Authoritative, where 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.

Affects: dnsreplay from 4.0.0 up to and including 4.1.1
