squid: incorrect X509 server certificate validation (SQUID-2015:1)
Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, do not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate.
It was found that Squid configured with client-first SSL-bump did not correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a Squid server using a specially crafted X.509 certificate.

CVE-2015-3455 [LOW] CVE-2015-3455 squid: incorrect X509 server certificate validation (SQUID-2015:1)
CVE-2015-3455 squid: incorrect X509 server certificate validation (SQUID-2015:1)
It was found that when Squid was configured with client-first SSL-bump it did not correctly validate X509 server certificate domain / host name fields. A man-in-the-middle attacker could use this flaw to spoof a Squid server using a specially crafted X.509 certificate.
This flaw is only exploitable Squid is configured to perform SSL Bumping with the "client-first" or "bump" mode of operation. Sites that do not use SSL-Bump are not vulnerable.
This flaw is fixed in Squid versions 3.5.4, 3.4.13, 3.3.14, and 3.2.14. All Squid-2.x, 3.0 and 3.1 are not vulnerable to this flaw.
