CVE-2018-1046 (GCVE-0-2018-1046)

Vulnerability from cvelistv5 – Published: 2018-07-16 20:00 – Updated: 2024-08-05 03:44

Summary

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.

Severity

7 (High)
