Critical [CVE-2026-64193] Net::DNS: Net::DNS: Arbitrary code execution via EDNS EXTENDED ERROR handling
CVE-2026-64193Source published Source updated
Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR. Net::DNS::RR::OPT::EXTENDED_ERROR::_decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option (RFC 8914) by tokenising the raw bytes and passing the result to Perl's eval. There is some escaping done for $ and @, but not for backticks. This can be exploited for command execution if $pkt->edns->option('EXTENDED-ERROR') is called in array context, for example with a payload of {0:`""`} in EXTRA-TEXT. The affected component processes the `EXTRA-TEXT` field of an EDNS EXTENDED-ERROR option without properly escaping special characters, which allows for command injection. This enables an attacker to execute unauthorized commands on the system. Red Hat severity: Critical — CVSS 9.8…
