CVE-2026-67198

Perspective 5.0.0 contains a denial-of-service vulnerability in the VirtualServer protocol dispatcher that allows unauthenticated remote attackers to crash the server process by sending malformed or incomplete protobuf messages. Attackers can send well-formed requests such as ViewToArrowReq with no viewport set or MakeTableReq with no data field to trigger unwrap() calls on None values at nine distinct sites, causing the process to abort with SIGABRT.

Summary		(es) Perspective 5.0.0 contiene una vulnerabilidad de denegación de servicio en el despachador del protocolo VirtualServer que permite a atacantes remotos no autenticados bloquear el proceso del servidor enviando mensajes protobuf malformados o incompletos. Los atacantes pueden enviar solicitudes bien formadas como ViewToArrowReq sin un viewport configurado o MakeTableReq sin un campo de datos para activar llamadas a unwrap() en valores None en nueve sitios distintos, lo que provoca que el proceso aborte con SIGABRT.
