Summary
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug was found in runc prior to version 1.1.2 where `runc exec --cap` created processes with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during execve(2). This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container's bounding set. This bug has been fixed in runc 1.1.2. This fix changes `runc exec --cap` behavior such that the additional capabilities granted to the process being executed (as specified via `--cap` arguments) do not include inheritable capabilities. In addition, `runc spec` is changed to not set any inheritable capabilities in the created example OCI spec (`config.json`) file.

Se encontr\u00f3 un bug en runc versiones anteriores a 1.1.2 en el que \"runc exec --cap\" creaba procesos con capacidades de proceso heredables de Linux no vac\u00edas, creando un entorno Linux at\u00edpico y permitiendo a programas con capacidades de archivo heredables elevar esas capacidades al conjunto permitido durante execve(2). Este error no afectaba al sandbox de seguridad del contenedor, ya que el conjunto heredable nunca conten\u00eda m\u00e1s capacidades que las incluidas en el conjunto delimitador del contenedor. Este error ha sido corregido en runc versi\u00f3n 1.1.2. Esta correcci\u00f3n cambia el comportamiento de \"runc exec --cap\" de forma que las capacidades adicionales concedidas al proceso que est\u00e1 siendo ejecutando (especificadas por medio de los argumentos \"--cap\") no incluyen las capacidades heredables. Adem\u00e1s, \"runc spec\" ha sido modificado para que no establezca ninguna capacidad heredable en el archivo de especificaciones OCI de ejemplo creado (\"config.json\u0027)"
