Debian DSA-3327-1 : squid3 - security update

medium Nessus Plugin ID 85184
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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.


Upgrade the squid3 packages.

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.
