Descriptions

ftpd in linux-ftpd 0.17, and possibly other versions, performs a chdir before setting the UID, which allows local users to bypass intended access restrictions by redirecting their home directory to a restricted directory.

ftpd en linux-ftpd 0.17, y posiblemente otras versiones, efectúa un chdir antes de establecer el UID, lo cual permite a usuarios locales evitar las restricciones de acceso previstas redireccionando su directorio home a un directorio restringido.

The original fix for Netkit FTP server introduced a new vulnerability allowing the listing of any arbitrary directory with root group permissions due to a typo in the setgid() call. New fixed packages are available. Also, this update adds a second CVE reference which was not originally mentioned while it was covered by the original fix. Versions less than 0.17-r5 are affected.
