Debian Security Advisory DSA-4968-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
September 07, 2021 https://www.debian.org/security/faq
Package : haproxy
CVE ID : CVE-2021-40346
Ori Hollander reported that missing header name length checks in the
htx_add_header() and htx_add_trailer() functions in HAProxy, a fast and
reliable load balancing reverse proxy, could result in request smuggling
attacks or response splitting attacks.
Additionally this update addresses #993303 introduced in DSA 4960-1
causing HAProxy to fail serving URLs with HTTP/2 containing '//'.
For the stable distribution (bullseye), this problem has been fixed in
version 2.2.9-2+deb11u2.
We recommend that you upgrade your haproxy packages.
For the detailed security status of haproxy please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/haproxy
