CVE-2026-64194
CVE-2026-64194 updated by NVD
Summary
Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains. Net::DNS::DomainName::decode follows RFC 1035 compression pointers by recursing into itself with no depth limit. It is possible to construct a name which saturates the call stack (at least with larger TCP responses), leading to a potential Denial of Service. The guard `$link new(\$wire)` i.e. any point where the library decodes a DNS message from the network.
