Details

Yuriy M. Kaminskiy discovered that the Squid pinger utility incorrectly handled certain ICMPv6 packets. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly cause Squid to leak information into log files. (CVE-2016-3947)

Yuriy M. Kaminskiy discovered that the Squid cachemgr.cgi tool incorrectly handled certain crafted data. A remote attacker could use this issue to cause Squid to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-4051)

It was discovered that Squid incorrectly handled certain Edge Side Includes (ESI) responses. A remote attacker could possibly use this issue to cause Squid to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-4052, CVE-2016-4053, CVE-2016-4054)

Jianjun Chen discovered that Squid did not correctly ignore the Host header when absolute-URI is provided. A remote attacker could possibly use this issue to conduct cache-poisoning attacks. This issue only affected Ubuntu 14.04 LTS, Ubuntu 15.10 and Ubuntu 16.04 LTS. (CVE-2016-4553)
