This module is only enabled in the nginx-extras binary package.
In addition the following vulnerability has been fixed.
CVE-2021-3618
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise
For Debian 10 buster, these problems have been fixed in version 1.14.2-2+deb10u5.
We recommend that you upgrade your nginx packages.
For the detailed security status of nginx 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]");
