    Harry Sintonen discovered that wget, a network utility to retrieve files
    from the web, does not properly handle '\r\n' from continuation lines
    while parsing the Set-Cookie HTTP header. A malicious web server could
    use this flaw to inject arbitrary cookies to the cookie jar file, adding
    new or replacing existing cookie values.
    
    For the oldstable distribution (jessie), this problem has been fixed
    in version 1.16-1+deb8u5.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 1.18-5+deb9u2.
    
    We recommend that you upgrade your wget packages.
    
    For the detailed security status of wget please refer to its security
