Alex Rousskov of The Measurement Factory discovered that Squid3, a fully featured web proxy cache, does not correctly handle CONNECT method peer responses when configured with cache_peer and operating on explicit proxy traffic. This could allow remote clients to gain unrestricted access through a gateway proxy to its backend proxy. For the oldstable distribution (wheezy), this problem has been fixed in version 3.1.20-2.2+deb7u3. For the stable distribution (jessie), this problem has been fixed in version 3.4.8-6+deb8u1. For the unstable distribution (sid), this problem has been fixed in version 3.5.6-1. We recommend that you upgrade your squid3 packages.
