Package : squid3
Version : 3.1.20-2.2+deb7u7
CVE ID : CVE-2016-10002
Debian Bug : 848493

Saulius Lapinskas from Lithuanian State Social Insurance Fund Board
discovered that Squid3, a fully featured web proxy cache, does not
properly process responses to If-None-Modified HTTP conditional
requests, leading to client-specific Cookie data being leaked to other
clients. A remote attacker can take advantage of this flaw to discover
private and sensitive information about another client's browsing
session.

For Debian 7 "Wheezy", these problems have been fixed in version
3.1.20-2.2+deb7u7.

We recommend that you upgrade your squid3 packages.
