Updated squid packages fix security vulnerabilities

Updated squid packages fix security vulnerabilities: Due to a buffer overrun, the Squid pinger binary in Squid before 3.5.16 is vulnerable to a denial of service or information leak attack when processing ICMPv6 packets. This bug also permits the server response to manipulate other ICMP and ICMPv6 queries processing to cause information leaks (CVE-2016-3947). Due to incorrect bounds checking, Squid before 3.5.16 is vulnerable to a denial of service attack when processing HTTP responses (CVE-2016-3948).
