Debian LTS: Security Advisory for haproxy (DLA-3034-1)

The remote host is missing an update for the 'haproxy' package(s) announced via the DLA-3034-1 advisory.

Nathan Davison discovered that HAProxy, a load balancing reverse proxy, did not correctly reject requests or responses featuring a transfer-encoding header missing the 'chunked' value which could facilitate a HTTP request smuggling attack. Furthermore several flaws were discovered in DNS related functions that may trigger infinite recursion leading to a denial of service or to information leakage due to a out-of-bounds read.

'haproxy' package(s) on Debian Linux.

Checks if a vulnerable package version is present on the target host.

For Debian 9 stretch, these problems have been fixed in version 1.7.5-2+deb9u1. We recommend that you upgrade your haproxy packages.
