Descriptions

fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O.

fs/open.c en el kernel de Linux anterior a v2.6.22 no elimina de forma adecuada los bits "setuid" y "setgid" cuando los escribe en un fichero , lo que permite a usuarios locales obtener privilegios de grupos diferentes, y obtener información sensible o posiblemente tener otro impacto no especificado, creando un fichero ejecutable en el directorio setgid a través de las funciones (1) truncate o (2) ftruncate en conjunción con una E/S mapeada en memoria.
