Detail
| Tim Düsterhus 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 |
