Red Hat Security Advisory 2017-0183-01 - The squid34 packages provide version 3.4 of Squid, a high-performance proxy caching server for web clients, supporting FTP, Gopher, and HTTP data objects. Security Fix: It was found that squid did not properly remove connection specific headers when answering conditional requests using a cached request. A remote attacker could send a specially crafted request to an HTTP server via the squid proxy and steal private data from other connections.
