    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.
