Summary

Updated squid packages fix security vulnerability:
Due to an integer overflow bug Squid is vulnerable to credential replay and remote code execution attacks against HTTP Digest Authentication tokens. When memory pooling is used this problem allows a remote client to replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. When memory pooling is disabled this problem allows a remote client to perform remote code execution through the free'd nonce credentials (CVE-2020-11945).
