CVE-2016-2571
http.cc in Squid 3.x before 3.5.15 and 4.x before 4.0.7 proceeds with the storage of certain data after a response-parsing failure, which allows remote HTTP servers to cause a denial of service (assertion failure and daemon exit) via a malformed response.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
