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 tracker page at: [link moved to references]");
