5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

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.

Affected configurations

• squid-cache squid 3.1.6
