Package : haproxy
CVE ID : CVE-2023-0836

It was reported that HAProxy, a fast and reliable load balancing reverse
proxy, does not properly initialize connection buffers when encoding the
FCGI_BEGIN_REQUEST record. A remote attacker can take advantage of this
flaw to cause an information leak.

For the stable distribution (bullseye), this problem has been fixed in
version 2.2.9-2+deb11u5.

We recommend that you upgrade your haproxy packages.

tracker page at:
