CVE-2024-7254

Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups / series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker.

Summary		(es) Cualquier proyecto que analice datos de Protocol Buffers no confiables que contengan una cantidad arbitraria de grupos anidados o series de etiquetas SGROUP puede corromperse si se excede el límite de la pila, es decir, StackOverflow. Analizar grupos anidados como campos desconocidos con DiscardUnknownFieldsParser o el analizador Java Protobuf Lite, o contra campos de mapa Protobuf, crea recursiones ilimitadas que pueden ser utilizadas de forma abusiva por un atacante.
