CVE-2015-0881
CRLF injection vulnerability in Squid before 3.1.1 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted header in a response.
Does this matter?
Lower severity and a low EPSS score (4.51%). Track it; it rarely justifies an emergency change on its own.
