Descriptions

In FreeBSD 12.0-STABLE before r350261, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350263, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, system calls operating on file descriptors as part of mqueuefs did not properly release the reference allowing a malicious user to overflow the counter allowing access to files, directories, and sockets opened by processes owned by other users.

En FreeBSD versión 12.0-STABLE anterior a r350261, versión 12.0-RELEASE anterior a 12.0-RELEASE-p8, versión 11.3-STABLE anterior a r350263, versión 11.3-RELEASE anterior a 11.3-RELEASE-p1, y versión 11.2-RELEASE anterior a 11.2-RELEASE-p12, las llamadas de sistema operando sobre descriptores de archivo como parte de mqueuefs, no liberaron correctamente la referencia, permitiendo a un usuario malicioso desbordar el contador, lo que permite el acceso a archivos, directorios y sockets abiertos por parte de procesos que son propiedad de otros usuarios.
