Security fix for CVE-2014-8517

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A malicious HTTP server could cause ftp(1) to execute arbitrary commands. Impact : When operating on HTTP URIs, the ftp(1) client follows HTTP redirects, and uses the part of the path after the last '/' from the last resource it accesses as the output filename if '-o' is not specified.

If the output file name provided by the server begins with a pipe ('|'), the output is passed to popen(3), which might be used to execute arbitrary commands on the ftp(1) client machine.

The remote host is running a version of Mac OS X 10.8 or 10.9 that does not have Security Update 2015-001 applied. This update contains several security-related fixes for the following components :

  - AFP Server
  - Bluetooth
  - CoreGraphics
  - CoreSymbolication
  - FontParser
  - Foundation
  - Intel Graphics Driver
  - IOAcceleratorFamily
  - IOHIDFamily
  - Kernel

  - libnetcore
  - LoginWindow
  - lukemftp
  - OpenSSL
  - Sandbox
  - SceneKit
  - Security
  - security_taskgate
  - Spotlight
  - sysmond

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

tnftp was updated to fix the possible execution of commands by a remote attacker (CVE-2014-8517).

The remote host is affected by the vulnerability described in GLSA-201611-05 (tnftp: Arbitrary code execution)

          The fetch_url function in usr.bin/ftp/fetch.c allows remote             attackers to execute arbitrary commands via a   Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process.
  Workaround :

    There is no known workaround at this time.
