Descriptions

The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

El kernel de Linux v2.6.33.2 y anteriores, cuando esta sobre un sistema de fichero ReiserFS, no restringe adecuadamente la lectura o escritura al directorio .reiserfs_priv, lo que permite a usuarios locales conseguir privilegios mediante la modificación de (1) atributos extendidos o (2) ACLs, como se demuestra mediante el borrado de un fichero bajo .reiserfs_priv/xattrs/.
