For Debian 10 buster, this problem has been fixed in version 1.8.19-1+deb10u4.

We recommend that you upgrade your haproxy packages.

For the detailed security status of haproxy please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
