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

Related Vulnerabilities: CVE-2004-0148   CVE-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.
