CVE-2016-3947 is a vulnerability of currently unknown severity. Heap-based buffer overflow in the Icmp6::Recv function in icmp/Icmp6.cc in the pinger utility in Squid before 3.5.16 and 4.x before 4.0.8 allows remote servers to cause a denial of service (performance degradation or transition failures) or write sensitive information to log files via an ICMPv6 packet.. EPSS estimates a 14.35% chance of exploitation in the next 30 days.
