Existe uma possibilidade de DoS na gem net-imap. Esta vulnerabilidade foi atribuída ao identificador CVE [CVE-2025-25186](https://www.cve.org/CVERecord?id=CVE-2025-25186). Recomendamos atualizar a gem net-imap.

## Detalhes

Um servidor malicioso pode enviar dados uid-set altamente compactados, que são lidos automaticamente pelo thread receptor do cliente. O parser de resposta usa Range#to_a para converter os dados uid-set em arrays de inteiros, sem limitação no tamanho expandido dos intervalos.

Atualize a gem net-imap para a versão 0.3.8, 0.4.19, 0.5.6 ou posterior.

## Versões afetadas

* gem net-imap entre 0.3.2 e 0.3.8, 0.4.0 e 0.4.19, ou 0.5.0 e 0.5.6
