An updated ncpfs package is now available. This update has been rated as having moderate security impact by the Red Hat Security Response Team.
Ncpfs is a file system that understands the Novell NetWare(TM) NCP protocol. A bug was found in the way ncpfs handled file permissions. ncpfs did not sufficiently check if the file owner matched the user attempting to access the file, potentially violating the file permissions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0013 to this issue. All users of ncpfs are advised to upgrade to this updated package, which contains backported fixes for this issue.
