Squid 3.x < 3.5.16, 4.0.x < 4.0.8 Multiple Vulnerabilities

The specific version of Squid that the system is running is reportedly affected by the following vulnerabilities:

• Squid contains an overflow condition in the Icmp6::Recv() function in icmp/Icmp6.cc of the pinger binary. The issue is triggered as user-supplied input is not properly validated when handling specially crafted ICMPv6 packets. This may allow a remote attacker to cause a buffer overflow, crashing the pinger process or potentially leaking data into log files. (CVE-2016-3947)

• Squid contains a flaw that is triggered as bounds are not properly checked when processing HTTP responses. This may allow a remote attacker to cause a denial of service for all clients accessing the service. (CVE-2016-3948)
