Debian Security Advisory DSA-4577-1 security@debian.org
https://www.debian.org/security/ Sebastien Delafond
November 28, 2019 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : haproxy
CVE ID : CVE-2019-19330
Tim Dusterhus discovered that haproxy, a TCP/HTTP reverse proxy, did
not properly sanitize HTTP headers when converting from HTTP/2 to
HTTP/1. This would allow a remote user to perform CRLF injections.
For the stable distribution (buster), this problem has been fixed in
version 1.8.19-1+deb10u1.
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
