New Revision: 435895
URL: https://svnweb.freebsd.org/changeset/ports/435895

Log:
  Adress CVE-2017-6410 in devel/kf5-kio and x11/kdelibs4
  
  Using a malicious PAC file, and then using exfiltration methods in the PAC
  function FindProxyForURL() enables the attacker to expose full https URLs.
  
  This is a security issue since https URLs may contain sensitive
  information in the URL authentication part (user:password@host), and in the
  path and the query (e.g. access tokens).
  
  This attack can be carried out remotely (over the LAN) since proxy settings
  allow ``Detect Proxy Configuration Automatically''
  This setting uses WPAD to retrieve the PAC file, and an attacker who has access
  to the victim's LAN can interfere with the WPAD protocols (DHCP/DNS+HTTP)
  and inject his/her own malicious PAC instead of the legitimate one.
