The flaws in the HTTP Digest Authentication processing, the HTTP Basic Authentication processing and in the cachemgr.cgi allowed remote attackers to perform denial of service and cross-site scripting attacks, and potentially the execution of arbitrary code.

For the stable distribution (buster), these problems have been fixed in version 4.6-1+deb10u1.

We recommend that you upgrade your squid packages.

For the detailed security status of squid please refer to its security tracker page at: [link moved to references]");
