Name of the Vulnerable Software and Affected Versions BC-JAVA versões anteriores a 1.84

Description Um problema nos módulos bcpg permite que o tamanho do chunk PGP AEAD seja ilimitado, o que pode levar à exaustão de recursos antes da autenticação. A exaustão de recursos ocorre quando um sistema carece de limites ou controle na alocação de recursos, permitindo que um solicitante consuma toda a memória ou CPU disponível do sistema.

Recommendations Atualize para a versão 1.84 ou posterior.
