Synopsis

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

Description

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 clients browsing session.

Solution

Upgrade the squid3 packages.

For the stable distribution (jessie), this problem has been fixed in version 3.4.8-6+deb8u4. In addition, this update includes a fix for \#819563.
