Descriptions

The ASN.1 parser in strongSwan before 5.5.3 improperly handles CHOICE types when the x509 plugin is enabled, which allows remote attackers to cause a denial of service (infinite loop) via a crafted certificate.

El analizador ASN.1 en strongSwan anterior a versión 5.5.3, maneja inapropiadamente los tipos CHOICE cuando el plugin x509 está habilitado, lo que permite a los atacantes remotos causar una denegación de servicio (bucle infinito) por medio de un certificado diseñado.
