A flaw was found in the way Squid handled malformed HTTP Range headers. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid. (CVE-2014-3609)

A buffer overflow flaw was found in Squid’s DNS lookup module. A remote attacker able to send HTTP requests to the Squid proxy could use this flaw to crash Squid. (CVE-2013-4115)

After installing this update, the squid service will be restarted automatically.
