Debian Bug     : 888719 888720

Several vulnerabilities have been discovered in Squid3, a fully featured
web proxy cache. The Common Vulnerabilities and Exposures project
identifies the following issues:

CVE-2018-1000024

    Louis Dion-Marcil discovered that Squid does not properly handle
    processing of certain ESI responses. A remote server delivering
    certain ESI response syntax can take advantage of this flaw to cause
    a denial of service for all clients accessing the Squid service.
    This problem is limited to the Squid custom ESI parser.

    service vulnerability when processing ESI responses or downloading
    intermediate CA certificates. A remote attacker can take advantage
    of this flaw to cause a denial of service for all clients accessing
    the Squid service.
