Synopsis

The remote Debian host is missing a security update.

Description

A security issue has been discovered in the Squid chaching proxy, on its 2.7.STABLE9 version branch.

CVE-2016-4554

Jianjun Chen found that Squid was vulnerable to a header smuggling attack that could lead to cache poisoning and to bypass of same-origin security policy in Squid and some client browsers.

For Debian 7 'Wheezy', this issue has been fixed in version 2.7.STABLE9-4.1+deb7u2.

We recommend that you upgrade your squid packages.

Solution

Upgrade the affected squid, and squid-common packages.
