    Updated squid packages fix security vulnerabilities:
    
    Jeriko One discovered that Squid incorrectly handled memory when connected
    to an FTP server. A remote attacker could possibly use this issue to obtain
    sensitive information from Squid memory (CVE-2019-12528).

    A remote attacker could possibly use this issue to access server resources
    prohibited by earlier security filters (CVE-2020-8449).
    
    Guido Vranken discovered that Squid incorrectly handled certain buffer
    operations when acting as a reverse proxy. A remote attacker could use this
    issue to cause Squid to crash, resulting in a denial of service, or possibly
    execute arbitrary code (CVE-2020-8450).
    
    Aaron Costello discovered that Squid incorrectly handled certain NTLM
    authentication credentials. A remote attacker could possibly use this issue
