CVE-2010-2951 is a vulnerability of currently unknown severity. dns_internal.cc in Squid 3.1.6, when IPv6 DNS resolution is not enabled, accesses an invalid socket during an IPv4 TCP DNS query, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via vectors that trigger an IPv4 DNS response with the TC bit set.. EPSS estimates a 31.46% chance of exploitation in the next 30 days.
