Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2921-1 advisory.

 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)
