Descriptions

An issue was discovered in adns before 1.5.2. pap_mailbox822 does not properly check st from adns__findlabel_next. Without this, an uninitialised stack value can be used as the first label length. Depending on the circumstances, an attacker might be able to trick adns into crashing the calling program, leaking aspects of the contents of some of its memory, causing it to allocate lots of memory, or perhaps overrunning a buffer. This is only possible with applications which make non-raw queries for SOA or RP records.

Se detectó un problema en adns versiones anteriores a 1.5.2. pap_mailbox822 no comprueba apropiadamente st desde adns__findlabel_next. Sin esto, puede ser usado un valor de pila no inicializado como la primera longitud de etiqueta. Dependiendo de las circunstancias, un atacante podría engañar a los publicistas para que bloqueen el programa de llamada, filtrando aspectos del contenido de parte de su memoria, causando que asigne mucha memoria o quizás el desbordamiento de un búfer. Esto solo es posible con aplicaciones que realizan consultas sin no procesar para registros SOA o RP
