Descripción
*** Pendiente de traducción *** Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains.<br />
<br />
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.<br />
<br />
The guard `$link new(\$wire)` i.e. any point where the library decodes a DNS message from the network.
