Package : pound
Version : 2.6-6+deb8u2
CVE ID : CVE-2016-10711
An issue has been found in pound,
A request smuggling vulnerability was discovered in pound, a everse proxy,
load balancer and HTTPS front-end for Web servers, that may allow
attackers to send a specially crafted http request to a web server or
reverse proxy while pound may see a different set of requests.
This facilitates several possible exploitations, such as partial cache
poisoning, bypassing firewall protection and XSS.
For Debian 8 "Jessie", this problem has been fixed in version
2.6-6+deb8u2.
We recommend that you upgrade your pound packages.
