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.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7203-1 advisory.

    Wei Hao discovered that PowerDNS Authoritative Server incorrectly handled memory when accessing certain     files. An attacker could possibly use this issue to achieve arbitrary code execution. (CVE-2018-1046)

    It was discovered that PowerDNS Authoritative Server and PowerDNS Recursor incorrectly handled memory when     receiving certain remote input. An attacker could possibly use this issue to cause denial of service.
    (CVE-2018-10851)

    Kees Monshouwer discovered that PowerDNS Authoritative Server and PowerDNS Recursor incorrectly handled     request validation after having cached malformed input. An attacker could possibly use this issue to cause     denial of service. (CVE-2018-14626)

    Toshifumi Sakaguchi discovered that PowerDNS Recursor incorrectly handled requests after having cached     malformed input. An attacker could possibly use this issue to cause denial of service. (CVE-2018-14644)
