certificate validation helper are vulnerable to a Denial of Service attack when
processing TLS certificates. This attack is limited to Squid built with OpenSSL
features and opening peer or server connections for HTTPS traffic and SSL-Bump
server handshakes (CVE-2020-14058).

Due to incorrect input validation Squid is vulnerable to a Request Smuggling
and Poisoning attack against the HTTP cache. This attack requires an upstream
server to participate in the smuggling and generate the poison response
sequence. Most popular server software are not vulnerable to participation in
this attack (CVE-2020-14059).");
