CVE-2016-4051

CESG and Yuriy M. Kaminskiy discovered that Squid cachemgr.cgi was vulnerable to a buffer overflow when processing remotely supplied inputs relayed through Squid.

CVE-2016-4052

CESG discovered that a buffer overflow made Squid vulnerable to a Denial of Service (DoS) attack when processing ESI responses.

CVE-2016-4053

CESG found that Squid was vulnerable to public information disclosure of the server stack layout when processing ESI responses.

CVE-2016-4054

CESG discovered that Squid was vulnerable to remote code execution when processing ESI responses.

CVE-2016-4554

Jianjun Chen found that Squid was vulnerable to a header smuggling attack that could lead to cache poisoning and to bypass of same-origin security policy in Squid and some client browsers.

CVE-2016-4555

and CVE-2016-4556

'bfek-18' and '@vftable' found that Squid was vulnerable to a Denial of Service (DoS) attack when processing ESI responses, due to incorrect pointer handling and reference counting.

For Debian 7 Wheezy, these issues have been fixed in squid3 version 3.1.20-2.2+deb7u5. We recommend you to upgrade your squid3 packages.");
