Descriptions

The caching functionality in the TrustManagerImpl class in TrustManagerImpl.java in Conscrypt in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49H, and 6.x before 2016-03-01 mishandles the distinction between an intermediate CA and a trusted root CA, which allows man-in-the-middle attackers to spoof servers by leveraging access to an intermediate CA to issue a certificate, aka internal bug 26232830.

La funcionalidad de almacenamiento en caché en la clase TrustManagerImpl en TrustManagerImpl.java en Conscrypt en Android 4.x en versiones anteriores a 4.4.4, 5.x en versiones anteriores a 5.1.1 LMY49H y 6.x en versiones anteriores a 2016-03-01 no maneja correctamente la distinción entre un CA intermedio y un CA root de confianza, lo que permite a atacantes man-in-the-middle suplantar servidores aprovechando el acceso a un CA intermedio para emitir un certificado, también conocida como error interno 26232830.
