Debian DLA-1280-1 : pound security update

A request smuggling vulnerability was discovered in pound 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 7 ‘Wheezy’, these problems have been fixed in version 2.6-2+deb7u2.

We recommend that you upgrade your pound 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.
