Topic: Updated gftp packages that fix a security issue are now available. gFTP is a multi-threaded FTP client for the X Window System. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 3. Problem description: A directory traversal vulnerability was discovered in gftp. A remote malicious FTP server could read, overwrite or create arbitrary files via .. (dot dot) sequences in the filenames returned from a LIST command. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0372 to this issue. Users of gftp are advised to upgrade to these errata packages, which contain a backported patch correcting this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.
