I just launched the latest Bitnami LAMP solution we published in AWS and found that we are using the latest package of OpenSSL
$ apt list --installed | grep openssl
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
openssl/stable,stable,now 1.1.1d-0+deb10u3 amd64 [installed,automatic]
However, that package is still vulnerable to the vulnerability you reported.
Once Debian updates the package, you should be able to update it as well using the apt package manager and the security vulnerability will be solved.
Happy to help!
