Multiple security issues were discovered in the Squid proxy caching server, which could result in the bypass of security filters, information disclosure, the execution of arbitrary code or denial of service.

For the stable distribution (buster), these problems have been fixed in version 4.6-1+deb10u2.

We recommend that you upgrade your squid packages.
