Package : haproxy
Version : 1.7.5-2+deb9u1
CVE ID : CVE-2018-20102 CVE-2018-20103 CVE-2019-18277
Debian Bug : 916308 916307
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.
For Debian 9 stretch, these problems have been fixed in version
1.7.5-2+deb9u1.
We recommend that you upgrade your haproxy packages.
For the detailed security status of haproxy please refer to
its security tracker page at:
