squid3 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Squid.

Software Description:
- squid3: Web proxy cache server

Details:

Sebastian Krahmer discovered that Squid incorrectly handled certain SNMP
requests. If SNMP is enabled, a remote attacker could use this issue to
cause Squid to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2014-6270)

Alex Rousskov discovered that Squid incorrectly handled certain malformed
responses. A remote attacker could possibly use this issue to cause Squid
to crash, resulting in a denial of service. (CVE-2016-2571)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
squid3 3.3.8-1ubuntu16.2

Ubuntu 14.04 LTS:
squid3 3.3.8-1ubuntu6.6

Ubuntu 12.04 LTS:
