Ubuntu Security Notice USN-2995-1
Posted Jun 9, 2016
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2995-1 - 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. 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. Various other issues were also addressed.

Red Hat Security Advisory 2016-1140-01
Posted May 31, 2016
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2016-1140-01 - The "squid34" packages provide version 3.4 of Squid, a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. Note that apart from "squid34", this version of Red Hat Enterprise Linux also includes the "squid" packages which provide Squid version 3.1. Security Fix: A buffer overflow flaw was found in the way the Squid cachemgr.cgi utility processed remotely relayed Squid input. When the CGI interface utility is used, a remote attacker could possibly use this flaw to execute arbitrary code.

Red Hat Security Advisory 2016-1139-01

Red Hat Security Advisory 2016-1139-01 - Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. Security Fix: A buffer overflow flaw was found in the way the Squid cachemgr.cgi utility processed remotely relayed Squid input. When the CGI interface utility is used, a remote attacker could possibly use this flaw to execute arbitrary code. Buffer overflow and input validation flaws were found in the way Squid processed ESI responses. If Squid was used as a reverse proxy, or for TLS/HTTPS interception, a remote attacker able to control ESI components on an HTTP server could use these flaws to crash Squid, disclose parts of the stack memory, or possibly execute arbitrary code as the user running Squid.
