Descriptions

Wire-ios is a messaging application using the wire protocol on apple's ios platform. In versions prior to 3.95 malformed resource identifiers may render the iOS Wire Client completely unusable by causing it to repeatedly crash on launch. These malformed resource identifiers can be generated and sent between Wire users. The root cause lies in [wireapp/wire-ios-transport](https://github.com/wireapp/wire-ios-transport), where code responsible for removing sensible tokens before logging may fail and lead to a crash (Swift exception) of the application. This causes undesirable behavior, however the (greater) Wire system is still functional. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

Wire-ios es una aplicación de mensajería que usando el protocolo wire en la plataforma ios de apple. En versiones anteriores a 3.95, los identificadores de recursos malformados pueden hacer que el cliente Wire de iOS sea completamente inusable al causar que sea bloqueado repetidamente al iniciarse. Estos identificadores de recursos malformados pueden ser generados y enviados entre usuarios de Wire. La causa root es encontrada en [wireapp/wire-ios-transport](https://github.com/wireapp/wire-ios-transport), donde el código responsable de eliminar los tokens confidenciales antes del registro puede fallar y conllevar a un fallo (excepción Swift) de la aplicación. Esto causa un comportamiento no deseable, sin embargo el sistema Wire (mayor) sigue siendo funcional. Es recomendado a usuarios actualizar lo antes posible. No se presentan medidas de mitigación conocidas para este problema
