Red Hat Security Advisory 2015-2378-01 - Squid is a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. 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. This update fixes the following bugs: Previously, the squid process did not handle file descriptors correctly when receiving Simple Network Management Protocol requests. As a consequence, the process gradually accumulated open file descriptors. This bug has been fixed and squid now handles SNMP requests correctly, closing file descriptors when necessary.
