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.
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.
