Descriptions

The encoding/xml package in Go versions 1.15 and earlier does not correctly preserve the semantics of directives during tokenization round-trips, which allows an attacker to craft inputs that behave in conflicting ways during different stages of processing in affected downstream applications.

El paquete encoding/xml en Go versiones 1.15 y anteriores no conserva correctamente la semántica de las directivas durante los viajes de ida por vuelta del proceso de generación de token, que permite a un atacante diseñar entradas que se comportan de manera conflictiva durante las diferentes etapas de procesamiento en las aplicaciones previas afectadas
