Package        : wu-ftpd
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2004-0148 CAN-2004-0185

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.

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

For the unstable distribution (sid) these problems have been fixed in
version 2.6.2-17.1.

We recommend that you update your wu-ftpd package.
