Due to incorrect input validation and URL request handling it was possible to bypass access restrictions for restricted HTTP servers and to cause a denial-of-service.

For Debian 9 stretch, these problems have been fixed in version 3.5.23-5+deb9u2.

We recommend that you upgrade your squid3 packages.

For the detailed security status of squid3 please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
