CVE-2011-1154

La función shred_file en logrotate.c en logrotate v3.7.9 y anteriores puede permitir a atacantes dependiendo del contexto, ejecutar comandos vía metacaracteres de la shell en un fichero de registro, como lo demuestra un nombre de archivo que es contruido de forma automática sobre la base de un nombre de host o máquina virtual.

Race condition in the createOutputFile function in logrotate.c in logrotate 3.7.9 and earlier allows local users to read log data by opening a file before the intended permissions are in place. The shred_file function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to execute arbitrary commands via shell metacharacters in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name. The writeState function in logrotate.c in logrotate 3.7.9 and earlier might allow context-dependent attackers to cause a denial of service character in a log filename, as demonstrated by a filename that is automatically constructed on the basis of a hostname or virtual machine name.
