This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service. Due to unrelated changes Squid-3.5 has become vulnerable to some regular ESI server responses also triggering this issue. This problem is limited to the Squid custom ESI parser. Squid built to use libxml2 or libexpat XML parsers do not have this problem. Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses or downloading intermediate CA certificates. This problem allows a remote client delivering certain HTTP requests in conjunction with certain trusted server responses to trigger a denial of service for all clients accessing the Squid service. last seen 2020-06-01 modified 2020-06-02 plugin id 106995 published 2018-02-26 reporter This script is Copyright (C) 2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/106995 title FreeBSD : squid -- Vulnerable to Denial of Service attack (d5b6d151-1887-11e8-94f7-9c5c8e75236a) NASL family Huawei Local Security Checks NASL id EULEROS_SA-2018-1074.NASL description According to the versions of the squid packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The Squid Software Foundation Squid HTTP Caching Proxy version 3.0 to 3.5.27, 4.0 to 4.0.22 contains a Incorrect Pointer Handling vulnerability in ESI Response Processing that can result in Denial of Service for all clients using the proxy..
