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


Charlie Smurthwaite of aTech Media discovered a flaw in HAProxy, a fast and reliable load balancing reverse proxy, when HTTP pipelining is used. A client can take advantage of this flaw to cause data corruption and retrieve uninitialized memory contents that exhibit data from a past request or session.


Upgrade the haproxy packages.

For the stable distribution (jessie), this problem has been fixed in version 1.5.8-3+deb8u1.
