Debian DLA-286-1 : squid3 security update

medium Nessus Plugin ID 85128


The remote Debian host is missing a security update.


Alex Rousskov discovered that Squid configured with cache_peer and operating on explicit proxy traffic does not correctly handle CONNECT method peer responses. In some configurations, it allows remote clients to bypass security in an explicit gateway proxy.

For Debian 6 Squeeze, this problem has been fixed in squid3 version 3.1.6-1.2+squeeze5. We recommend that you upgrade your squid3 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
