Debian DSA-457-1 : wu-ftpd - several vulnerabilities

critical Nessus Plugin ID 15294

Synopsis

The remote Debian host is missing a security-related update.

Description

Two vulnerabilities were discovered in wu-ftpd :

 - CAN-2004-0148 Glenn Stewart discovered that users could bypass the directory access restrictions imposed by the restricted-gid option by changing the permissions on their home directory. On a subsequent login, when access to the user's home directory was denied, wu-ftpd would fall back to the root directory.

 - CAN-2004-0185

 A buffer overflow existed in wu-ftpd's code which deals with S/key authentication.

Solution

For the stable distribution (woody) these problems have been fixed in version 2.6.2-3woody4.

We recommend that you update your wu-ftpd package.
